Solubility Rules and Compounds

The video tutorial covers solubility rules, explaining how to determine if a substance will dissolve in water. It introduces the solubility chart, highlighting soluble and insoluble compounds, and discusses exceptions to these rules. The tutorial also includes practice problems to apply the solubility rules, helping students understand how to predict the solubility of various compounds.

What is the purpose of the solubility chart?

• To calculate the pH of solutions

• To measure the temperature of reactions

• To identify the solubility of substances in water
