Ocean County College Department of Chemistry Ionic Reactions Submitted by: Date Submitted: July 10, 2014 Date Performed: July 8 2014 Lab Section: Chem 181-DL2 Course Instructor: Amal Bassa Background Aqueous solutions of ionic substances will be experimented with in this Ionic Reactions lab. Aqueous solutions are solutions that water is solvent. After ionic substances dissolve in water, ions separate and become surrounded by water molecules. When these ion separate, its called dissociation. Purpose The purpose of this experiment is to study ionic reactions, to be able to write balanced equations, and to be able to write net ionic equations for precipitation reactions. Procedure First, all…show more content…
