Chem 212- Lab Report 1: Solubility Introduction: The amount of solute that may dissolve in a solvent is referred to as solubility. Because the dissolution process between the solute and the solvent varies, a solute's solubilities in different solvents will vary. The temperature of the solution has an impact on solubility. Always double- check the temperature that corresponds to a solubility value. Temperature normally enhances solubility, although there are exceptions. Procedure: Part A: ...
