The Effect of Sodium Chloride on a Potato Chip To investigate what happens to a potato chip's weight when placed in different concentrations of Sodium Chloride INTRODUCTION:~ ============== Osmosis is defined as 'the movement of water molecules from an area of high water concentration to an area of low water concentration, across a semi-permeable membrane' (Collins, 1999). A semi-permeable membrane is a membrane that partially allows liquid to pass through. In the case of the experiment
Chemical Analysis of Preparing a Solution of Sodium Chloride One of the most common practices in the laboratory is accurately to prepare chemical solutions in the laboratory. I was given the task to prepare a one mole solution of sodium chloride for a precipitate experiment. The solution must be at a high level of accuracy to make sure the experiment works next week. Safety Points Sodium Chloride · Wear safety goggles · Do not eat · Use smallest amounts possible on a
DESCRIPTIVE TITLE The Effect of Different Amounts of Sodium Chloride on the displacement of oxygen. INTRODUCTION The dependability of the rate of an enzyme-mediated reaction is based on two factors: the substrate concentration and the concentration and action of the enzyme that catalyzes the reaction (Vander, et. al., 2001). Enzymes are catalysts that produce chemical reactions in cells. Enzymes which are large proteins perform a reaction which acts upon a substance known as a substrate. When
bottles thought to contain hydrochloric acid, or sodium chloride solution, or sodium hydroxide solution. Describe a simple experiment which would allow you to determine which bottle contains which solution. The simplest experiment for this type of situation would be to use red and blue litmus paper to distinguish between acids, bases and salts. Hydrochloric acid (HCl) makes blue litmus paper change color going from blue to red, making it an acid. Sodium hydroxide (NaOH) makes red litmus paper change
The Effect of the Amount of Sodium Chloride on the Electric Current During Electrolysis Background When an electric current passes through sodium chloride solution, chemical reactions take place at both cathode and anode. If one passes through sodium chloride solution, there will be passage of ions moving through this solution. This results in positively charged sodium ions, which have been dissolved into the solution, moving towards the cathode and deposited there. At the same time, negatively
The Effect of Sodium Chloride Concentration in Growing Medium on the Growth and Total Germination of Cress Seeds Scenario There are a number of things that can influence how/if a plant grows and germinate. These include; · Amount and intensity of sunlight. · CO2 concentration of the air. · Temperature and humidity of the atmosphere. · PH of the water and soil. · Salt concentration of the soil and water. · Quality of the soil, i.e. Minerals and nutrients. · Use of
An investigation into whether the voltage affects the amount of gas produced during the electrolysis of sodium chloride solution. Prediction: I think that hydrogen gas will be produced due to the half equation 2H +2e àH this will be produced at the cathode because opposites attract and the hydrogen ions are positive. At the anode I think that chlorine will be produced due to the half equation 2CL -2e àCL the chlorine ions are negative so they are attracted to the positive electrode. I also think
1. Sodium Chloride has a higher boiling point than water, so when salt is added to water, the solution has a higher boiling point than pure water. The sodium ions and chloride ions present in sodium chloride disassociate and dissolve in water. These ions interfere with the dipole interactions that occur between molecules of water. The dissolved sodium ions and chloride ions require more energy to separate from the water molecules in the solution than the water molecules from themselves, so the boiling
of answering the following question, is sodium chloride a viable option for reducing ice on Minnesota roads? The answer to this question relies heavily on how well sodium chloride decreases the freezing point when dissolved in water, as well cost and its environmental impact. To determine this, the freezing point of varying molality’s of sodium chloride were compared to pure deionized water. The results of this experiment revealed that as more sodium chloride was dissolved, the freezing point depression
even used in the process of mummification. Modern day chemists found several important ways to use salt. People use sodium today for softening water for drinking, flavoring foods, and for treatment of various medical conditions. Humans and animals with warm blood need salt to live and function properly. Salt serves as an extraordinary resource to the word in various ways. “Sodium chloride: Noun. Also called: salt or common table salt; a soluble colourless crystalline compound occurring naturally as
The researcher conducting this experiment is trying to find out which salt- Epsom, table salt, and sea salt- will increase the boiling point of water the most. Sodium chloride is believed to increase the boiling point of water because when salt is suspended into the water, the sodium and chlorine ions leave the “salt crystals” and mix with the water molecules. (“Why does salt… raise boiling point of water?”, 2009). People discovered salt around 900 B.C. They would dig up salt near the Dead Sea and
Project title of field of study The effect of soil salinity in plant growth is part of botany, the study of plants. Botany: the study and science of plants in a particular habitat and region, it is the branch of biology that deals with the life of plants. Soil Salinity, Should We Be Worried? Introduction Soil salinity is said to be “bad” for plant growth but is this really true? Is it just a big misunderstanding? Is it really the salts 'fault'? Are there no solutions to fixing this problem? These

Hydrochloric acid is the clear colourless solutions of hydrogen chloride (HCl) in water, hydrochloric acid is also a highly corrosive substance and a strong mineral acid meaning they are formed from inorganic compounds, hydrochloric acid is a monoprotic acid meaning that it can only ionize one H+ ion. As a result hydrochloric acid can be used in a wide range of industrial practices such as removing rust from steel, ore processing, the production of corn syrup and making of PVC plastics. Hydrochloric
relative to the concentration of carbonic acid, which shifts the pH to the alkaline side of the physiologic range (case study- pH 7.5). The main causes of metabolic alkalosis are loss of gastric juice or neutralization of gastric juice by antacids, chloride depletion, and excess adrenal corticosteroid hormones. Excessive amounts of gastric juice may be lost by prolonged vomiting (case study-several times daily x 8 days (?)). The loss of gastric juice causes loss of hydrogen ions. Alkalosis results
aqueous solution or in the molten state. All ionic compounds are electrolytes. The following elements are electrolytes in a persons body: sodium (Na+), potassium (K+), chloride (Cl-), calcium (Ca2+), magnesium (Mg2+), bicarbonate (HCO3-), phosphate (PO42-), and sulfate (SO42-). The most common of these elements that are typically found in drinks are sodium, potassium, and calciu... ... middle of paper ... ... with 20.6; and distilled water and tap water had the least with 0.1 and 3.1.

two areas of ground water, chloride concentration and sodium concentration. Chlorides may be present in the form of sodium chloride crystals or as a ion in a solution. Normal concentrations in the water are average around 10 mg/litre. Concentrations found in ground water near major highways have been recorded as high as 250 mg/litre which is around the threshold of taste. The main factor with ground water pollution is the risk to human health. The raised level in sodium in water can cause high blood
3 contained 0.2 mL of 1-chlorobutane and the tert-butyl chloride, when shaking the test with the product closed in by the cork the test tube products went from clear to dull yellow color. No precipitation was formed after 5 minutes; therefore, the test tube was placed in a 53 °C of water for an additional 5 minutes. Precipitation appear on the side of the test tube. Test tube 4 contained 0.2 mL of 1-chlorobutane and the tert-butyl chloride, no changes and no precipitation were form. Same as for test
usually formed by a bond with the metal groups and carries a negative charge; can also consist of polyatomic ions. Positive cations and negative ions remain bonded together by their electrical charges. Crystals with ionic properties, such as sodium chloride completely dissociates in water. Thus, ionic compound form crystal, they have a high melting point and known to dissolve evenly in aqueous solutions. Water molecules have conduction properties, which makes the dissociation process conducive. Consequently
