Chemistry 112: Anion Analysis Page 7 ANION ANALYSIS M uch of the work you will be doing in the Chemistry 112 laboratory will be concerned with identifying positive and negative ions‚ that is‚ cations and anions‚ in solutions whose composition is unknown. This procedure is called QUALITATIVE ANALYSIS. The modern chemist frequently wishes to identify the constituents in a very small amount of substance‚ and so he depends heavily on instrumental methods of analysis. While the procedures

PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

most enzymes have an optimum pH range of approximately 7. If the pH falls to either side of 7 it can impair or destroy the function and structure of the enzyme. According to the company ‘Patient Storm’ a new invention has discovered a method to stabilise an enzyme during freezing providing the enzyme in a zwitteronic buffer solution. A zwitterionic composition is useful as a surface active agent in aqueous solutions. The buffer solution has the capacity to stabilise an enzyme‚ such as glocuse
