Recommended: Effect of rusting
Rust is already part of life. Society can be able to witness jewelry, machinery, utensils and on every part of our home, school or in our society since the world is already in 21stwhere metals are commonly used in buildings and homes. They say that it iscustomary in the way that it’s already a sign that one is already getting older and weaker as days goes by. However, many researchers are conducting studies to remedy rusting and help society to free from this corrosion. This study is about to end the search for what is the best rust remover that can be found on every home. Rusting can be no more a threat to the safety and health of the person. As well as to the newness and looks of the items people consume. The use and importance of steel and …show more content…
Science said that opposite charges attract, so, in the case of Iron and Oxygen having opposite charges, the elements combine and then results to oxidation. Oxidation on the other hand, produces a chemical reaction forming Fe203 Iron Oxide or Ferric Oxide, otherwise commonly known as rust. When Iron is exposed to nature’s minerals, changing temperature and chemicals, the rusting process accelerates. However, Iron can be isolated from its destructive environment by coating it with paint, lacquer or varnish, moreover, rust formation is …show more content…
Some of these substances are vinegar, baking soda (Sodium bicarbonate) and Calamansi (Citrofortunellamicrocarpabunge) in which will be used as main independent variables in this research. Vinegar is a liquid comprising of water (H20), 5-20% acetic acid (CH3COOH) and other trace chemicals ( Anne Marie Helmenstine, Ph.D, “What Is the Chemical Composition of Vinegar,February 16, 2016.). It dissolve and loosen the crumbly hydrated iron oxide (rust) and replace it with a thin film of smooth hard oxide on the surface of the iron to help it resist further hydrated oxidation (“Why is vinegar such a good rust remover?”, Naked Science Forum ©2016). Baking soda (Sodium bicarbonate, NaHCO3) is a salt composed of sodium ions and bicarbonate ions, and has two environmental factors which is slightly alkaline and dry which tend to deter rusting (Ted Mooney, P.E. RET, “Why does Baking Soda Blasting prevent rust?”, 2008). Calamansi (Citrofortunellamicrocarpabunge) is a very native fruit tree in the Philippines and its extract is composed of ascorbic acid, phosphorus and calcium, which is then referred as an effective rust stain remover (Meg Hayes,“What Are The Chemical Components Of Calamansi
Iron is naturally iron oxide and purified iron rapidly returns to a similar state when exposed to air and water. This whole process can be seen below in figure 3 – ‘The corrosion

Iron is a trace element, which is a group of minerals present in small quantities in the body. Other trace elements include copper, zinc, selenium, manganese and iodine. These minerals cannot be synthesized by the body and must therefore be supplied in the diet. Iron is the most common trace element in the human body; adult males have approximately 3.5 g iron in total, or 50 mg per kg body weight while females have about 2g total iron or 35 mg per kg bodyweight. Iron can exist in oxidation states from -2 to +6, but mainly exists in the ferrous (+2) and ferric (+3) states in biological systems. As iron has the ability to accept and donate electrons readily, it can interconvert between these two forms with ease. Thus, iron can participate in
Iron is called a trace mineral, but its effects are mighty. We need it to produce hemoglobin, the oxygen carrier in red blood cells that brings oxygen to the rest of the body. Iron is also needed to produce myoglobin, the oxygen reservoir in the muscle cells.
1. Introduction Redox reaction between fingerprint sweat residue and the surface of metals is a major factor that causes corrosion on metals due to the presence of chlorides ions in fingerprint sweat. With exposure to sweat residue, chemical reaction happened between the interaction of sweat residue and the metal surface, which causes the metal surface to oxides and eventually degraded. Besides sweat, various controllable and uncontrollable factors, such as oxygen, moisture and environmental conditions are other factors that have an impact on how fast a metal corrodes. So, the aim of this discussion is to analyse the effects of sweat on metallic surfaces.

Pure iron has a hardness that ranges from 4 to 5. It is soft and ductile. Iron can be easily magnetized at ordinary temperatures and at 790°C the magnetic property disappears. Pure iron melts at about 1535°C, boils at 2750°C, and has a specific gravity of 7.86. Chemically, iron is an active metal. When exposed to humid air, iron forms a reddish-brown, flaky, decay known as rust.
Chemical: Acids in foods and beverages such as citrus fruits, spices, wines and carbonated beverages; acids produced by acidogenic bacteria following carbohydrate exposure; acids from gastric regulation. (Wilkins, BS, RDH, DMD, 2013)
I. Martensitic stainless steels have good mechanical strength and are moderately corrosion resistant. Because of their excellent corrosion resistance and mechanical strength, martensitic stainless steels are used for manufacturing the steam turbine blades, heat exchangers, automotive components and structures, petrochemical & process piping. Properties of martensitic stainless steel can be changed by the heat treatment. Increasing productivity of any welding process while maintaining or even improving the weld quality has been the task of researchers in the field of development of welding processes. Over the years, welding methods and techniques have developed to great extent [3].
So, to break up the dirt and remove it or to neutralize it, is for the cleaning products to have a basic ph (Dimaano). A common household product with a high alkaline or basic level is bleach, its chemical name is sodium hypochlorite, NaClO. It is corrosive, with the many different derivatives of the salt, which is required to whiten and remove the stain. This compound is either colorless or slightly yellow liquid, it is usually mixed with water (PubChem). It is an irritant on the skin and to eyes (PubChem). Now looking at Clorox bleach in my house, the active ingredient is Sodium Hypochlorite, which is a derivative of salt, meaning that is breaks down into oxidized salt and biodegradables. It also contains sodium chlorate, sodium hydroxide, sodium carbonate, all of which are high on the basic levels. Another cleaning product that is used a lot in my house, is dishwasher pods, specifically Cascade Platinum Action Pacs. The powder ingredients contain many polyatomic chemicals whereas the liquid ingredients contain more dyes to obtain the colors seen in the pacs. The first powder ingredient listed is sodium carbonate, methyl glycine diacetic acid, sodium sulfate, sodium percarbonate. Many of these contain sodium, which is generally seen in more basic compounds, such as dish soap or soap in general. Sodium has corrosive qualities, but in small quantities and mixed with other elements, it is used to
Stainless steel is a type of alloy that has a very strong lattice structure (an arrangement/ shape of the crystals or other objects) which in some case can be more beneficial than others depending on the type of application it may be used for. In many cases this structure will make the material more suited to being used in engineering applications such as tools for instance a hammer (stainless steel alloys) , also they can be used for gears, engines, electrical motors and hydraulic systems because the structure makes the material so strong. So when the arrangement of the structure is as above it makes the overall material even stronger which makes it a good for all the applications stated above. I believe its strength and durability are its main properties as these are commonly needed in the engineering industry, although it is also very well known to be used for its corrosion resistance as it is resistant to many types of corrosion. It is used for these properties because the components such as gears need to be strong in order to keep transferring and altering the rotary motion and torque exhibited in the machine that it may be used in, durable to withstand any loads or pressure put onto it and also corrosion resistance to give the components a bigger life span and increase its rate of work throughout its required use.
With the expansion of technology available to the textile industry emerged a growing want among those who produced the textiles for new colors. When this problem arose, textile producers called upon the chemistry industry to help lessen the need for textile producers to rely upon natural methods of bleaching such as sun, rain, sour milk, and urine (Britannica). While these methods had been practiced for centuries, the industry saw a definite want for a new and more efficient method of bleaching. From this point forth, chemistry’s role in the Industrial Revolution not only led to innovations in bleaching, but also led to great changes in the practice of chemistry, as we know it. In the mid-1700’s, a chemist named John Roebuck solved the problems of the textile industry with his invention of a new method for mass producing a chemical by-product known as sulfuric acid in lead chambers (Encarta 97). This discovery paved the way for sulfuric acid’s use in bleaching, and eventually led to the production of chlorine bleach, a common household product today.
Preventive maintenance can be defined as an activity performed on a certain schedule which is intended to prevent breakdowns or deterioration. These activities can include regular inspection along with solving any discovered problems or situations and regularly scheduled parts changes. Preventive maintenance involves the scheduled adjustment, inspection, replacement of wearable parts, calibrations, basic cleaning and lubrication of equipment or other recommendation made by the equipment manufacturer. These activities can help increase the equipment functional life and help decrease facilities deterioration. No equipment should, No equipment should reach the breaking point [1].
There are (nearly literally) a million types of polishing compounds on the planet, but no matter what you choose, you really shouldn’t cheap out on your compound. Better compounds deliver better results; clearly, you don’t...
Laundry detergents have had a great impact on the society since it helps our life in keeping ourselves clean, lessens our job or the use of our energy in cleaning our appliances. Laundry detergents have come a long way since the very first bar soaps, made from animal fat and lye, were offered for sale in the 1700s. In the 1950s, homemakers had more options of fabric care since the introduction of synthetic detergents were placed on the market. However; during the 1970s, the most significant innovation in advanced cleaning was made available to clean specific types of stains. Every detergent manufacturer has secret ingredients and mixtures to produce their specific brands of laundry detergent. Many of these ingredients are extracted from plants,
