Learning Objectives•Define solution and understand its components•Identify major classes of reactions•Write chemical equations for various reactions•Determine an appropriate sensor to monitor the course of a reaction
Solutions•Homogeneous mixtures of two or more substances•The solventis present in greatest abundanceIn most cases the solvent is water•All other substances are solutes(a)(b)(a) A homogeneous sugar solution and (b) its molecular-level representation. The water molecules are muted so the sugar molecules are easier to see.

Dissociation•When an ionic substance dissolves in water, the solvent pulls the individual ions from the crystal and solvates them•This process is called dissociation or dissolution(a) Ionic crystal (b) ionic crystal dissolving
