    Acids are substances that, when added to water produce hydrogen ions. Hydrogen Ions are the combination of hydrogen and water molecules. There are many types of acids, which consist of citric, hydrochloric, carbonic, sulfuric, acetic, nitric, phosphoric, and lactic acids. Acids react with zinc, magnesium, and aluminum forming hydrogen. They turn blue litmus paper red. Litmus is used to check for acidity. Acids are sour, react with metals to produce hydrogen gas, and react with carbonates to produce

    Does Concentrated Acid or Diluted Acid React Faster? Plan I am going to carry out a reaction between Magnesium ribbon and Hydrochloric acid. The aim of this investigation is to work out which reacts faster, concentrated acid or diluted acid. I will judge if the reaction is fast or slow by observing the bubbles which occur during the reaction and also observe if the Magnesium has disappeared. Only the concentration of the acid will be changed - the Magnesium is a solid. Magnesium +

    Acids and bases are not just in use in a laboratory, they come into play in the every-day, they are important to know, with respect to consumer and food products. PH scale, the potential for hydrogen ion concentration, is important because it pertains to the spectrum of acids and bases. Acids are an H+ donor and bases are a H+ acceptor. We can further identify acids by its sour taste, it turns litmus paper red, and it dissolves metals such as zinc or iron. Bases taste bitter, they turn litmus paper

    qualities. A lot of the things that human being eat and drink have different pH levels, which is why it is so important for humans to be knowledgeable on the difference between acids and bases to be able to balance the pH levels in their bodies to remain healthy. For one to determine whether or not a substance is an acid or a base, they first must know the types of ions the substance contains. Due to how wide the range is from a very acidic solution to a very basic solution scientists created a scale

    products can be acidic, bases or neutral. It was very interesting to learn that many acids are not dangerous. Some are even found in the food that we eat. Any food that taste sour is acidic. Bases are also found in common household products. They can be very strong and dangerous or weak and safer for use around the house. 2. INVESTIGATIVE QUESTION To prove how much acidic levels are in our household products and foods ACID BASE NEUTRAL Coffee Ammonia Olive Oil Lemon Juice Baking Soda Melted Butter Soda

    such as nitrogen, phosphorus, and potassium, are less available below a pH of 6.0. Iron, manganese, and phosphorus are less available when a pH level exceeds 7.5. Most garden plants grow well in slightly acid to neutral soil. This means the pH levels will range from 6.0 to 7.0. If soil is too acid, adding an alkaline material can neutralize it. This is a process commonly called liming. The most common liming material is ground limestone. If soil is too basic, adding a source of acidity will be beneficial

    life there are acids, bases, and salts. Some may not know how to see them or even what they are. You might put baking soda into vinegar to see what happens afterward. We put salts on our food to make it taste better. There is salt in every ocean on earth. There are so many acids, bases, and salts around us and we just do not see them. We eat a neutralizer when we get heartburn from the acid in our stomachs. Science is all around us. The Oberverable Properties of Acids An acid is a substance

    Hydrochloric acid (HCl): Hydrochloric acid is a strong and corrosive acid that is often used as a reagent in laboratories. It is made by dissolving hydrogen chloride in water. 17 Hydrochloric acid is polar substance and has a linear shape with an electronegativity difference of 0.9; it has weak dipole-dipole forces/bonds between its molecules (intermolecular forces) and polar covalent forces/bonds between the chloride and hydrogen ions (Intramolecular forces). (5) HCl has a molar mass of 36.4609

  • The Effects of Acids on Molds

    525 Words  | 2 Pages

    There is inadequate research/information on molds and how they are affected by acids. There is not sufficient information on the elimination or prevention of molds on household and grocery items. To test possible solutions, the growth of mold will be examined using different acids to help keep the mold at a low quantity. Two different substances, one with a high acidity and one with a low acidity, will be used along with water as our “mold repellants”. At the conclusion of each trial, each acid’s

    who said that sour tasting substances were oxein, later mutated into the word vinegar acetum which became to “acid”. These substances were eventually found out not only to define sour things, but also be able to change litmus paper and corrode metals. On the contrary, bases were defined and studied by their ability to counteract acids and followed behind chemical characterizations of acids. The more rigid term called alkaline is from an Arabic root word roasting because the first bases were from the

    Acids and Bases Acids are a material that releases a proton or hydrogen ion (H+). Acids always generate an H+ whenever the solution is aqueous, which can be easily identified. On the contrary, in an aqueous solution involving bases always produce an OH- ion. There are many different ways to identify whether a substance is an acid or a base. An acid is always sour, changes litmus, conduct an electric current, react with a base to form salt and water, and whenever there is a reaction, acids helps

    materials, this is known as acid rain. Acid rain is a huge problem all over the world. Acid rain is mixture of chemicals, like fossil fuels and the atmosphere, it then comes down as rain, snow, hail, and sleet. The burning of fossil fuels is the main cause of acid rain. When oil and coal are burned they create sulfur dioxide, nitric oxide, and nitrogen dioxide. (" Acid Rain | US EPA") The mixture of all the chemicals and heavy winds blow the compounds across many borders. Acid rain is measured by using

    Acid rain is a very big pollution problem in the world. It has killed fish and other aquatic life in many lakes and streams. It harms human health, disfigures monuments and erodes buildings, and, along with other pollutants, threatens forests. The story of acid rain can be compared to the plot of a science fiction movie. In the 1950s an invisible force begins to destroy lakes and rivers, killing trout and salmon. By the 1960s it is harming the waters of eastern Canada and the northeastern United

    1. Definition of Acid and Bases: 1.1 Arrhenius definition of acid and base: Arrhenius Acid: The substance or a compound which gives H+ ions in aqueous solution Arrhenius base: Base is a substance or compound that produces OH- ions in aqueous solutions. Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous solutions. It did not take longer

    of mixing various levels of acids and bases to see which combination would have the most explosive reaction, and measure the resulting pH levels. I did this by testing an assortment of different pH levels of acids and bases, mixing them together and measuring the results. Most of the experiments resulted in a pH neutral solution, except for the Sulfuric Acid and the Sodium Hydroxide. By far, the Sulfuric Acid was the most explosive, followed by the Citric and Acetic acid. Introduction The project
