General Chemistry laboratory, Chem18/19 Purpose: List of equipment: List of chemicals: Experiment # 11 Title: Qualitative analysis: Precipitation reactions and solubility The purpose of this lab is to learn how to observe data qualitatively, specifically by determining whether certain binary combinations of known solutions or cation-test solution combinations produce a precipitate or not based on a series of solubility rules. The qualitative observations are learned using color changes within solutions. This lab also introduces the variation of solubility of precipitates in acids and the
