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

Conductivity of Ionic and Molecular Aqueous Solutions Abstract Aqueous solutions that have free ions have higher conductivity values than solutions with most molecules. The purpose of the experiment was to see if ionic strength of an aqueous solution determines its conductivity. We tested each compound by putting the conductivity probe into its aqueous solution. Then the computer would analyze the data and give us a conductivity value. After each solution was tested‚ we used deionized water to

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending
