3. SAFETY AND ENVIRONMENTAL ASPECTS OF SULPHURIC ACID PRODUCTION 1. Safety Aspects 1. Basic Safety Aspects due to Physical properties and behaviour of Sulfuric acid. Basically, we know attention is paramount when adding water to a highly concentrated acid and this is the case with sulphuric acid which is highly risky. Sulfuric acid can have serious adverse effects like burns if it contacts the skin. This is due to the dehydrating properties of the acid on organic materials. Also, when the…
Question 1: pH can be described as a measure of acidity or basicity (Alkalinity) of a solution. It is exactly equal in amount to the negative log of the concentration of hydronium(H3O+) ions. Due to the negative log relationship, increased hydronium ions transform to lower pH. When we add it to water, an acid releases hydrogen ion. Hydrogen ions in water unite with the water molecules to form hydronium ions, thereby lowering the pH and increasing the acidity of water. Water exposed to air is…
ways. It is important and useful to know all the different types of reactions because they often refer the reactions as being of one type or another. The first reaction is Acid-base (Neutralization) Reaction. A neutralization reaction occurs when an acid and base are mixed together. The compound formed by the cation of the base and the anion of the acid is called a salt. The combination of hydrochloric acid and sodium hydroxide produces common table salt. An example is…
Introduction: Kidney stones are an extremely basic urinary issue. Also known as renal calculi, kidney stones are characterized by their high occurrence and a high repeat rate. This issue results from the arrangement of insoluble salt stores in the urinary tract and inside the kidney. The rate of this issue has expanded in the course of recent years for reasons that are not entirely known, but have caught the consideration of numerous scientists. There are different types of kidney stones, each…
water, which is made of hydrogen and oxygen, the hydrogen in the water can make a solution into an acid or a base. How do you tell if something is an acid or a base? You use a chemical called an indicator, which changes in color when it goes from an acidic to basic. There are many different types of indicators, some are liquids and some are concentrated…
Project 3 Identification and Synthesis of an Unknown Ionic Compound Mitchell Morgan CEM-161-007 Josh Ward 28th October 2015 Abstract The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was…
values greater than 7 are known to be bases, while those having pH equal to 7 is identified as neutral substances (Petrucci, 2011). Identifying its electrolytic property also helps to characterize the given solutions. Strong electrolytes, such as strong acids and bases and salts are known to fully dissociate its ions in the solution, making it a good conductor of electricity. On the other hand, the presence of weak electrolytes, such as weak acids and bases, do not dissociate its ions completely…
Background: Acidic rain or acid deposition is predominantly caused by air pollution. Acid deposition in the form of gasses and microscopic particles, floating in the air, is called dry deposition. However, wet deposition is in the form of precipitation. As a result of chemicals being released from human productions, great amounts of sulfur dioxide and nitrogen dioxide are respired into the atmosphere, where rain and gas matter is polluted. Once both sulfur dioxide and nitrogen dioxide come in…
matrix was constructed. The pH of each solution was measured and labeled from a strong base to a very strong acid. Then, react one of the unknown solution with all of the others and note any visible reaction (change in color or formation of precipitate) that occurs. After that, some the solutions might be identified throughout the…
The Case of the Mix-Matched Chemicals Hypothesis: By measuring the pH of the unknown and known chemicals, the types of chemicals in the unknown bottles will become known. Purpose: The purpose of this experiment is to determine the type of chemicals that are inside the mislabeled bottles. Materials: • pH strips • 8 bottles of known chemicals: o silver nitrate o iron (III) nitrate o copper (II) nitrate o sodium iodine o sodium hydroxide o nitric acid o lead (II) nitrate o sodium…
