Preparing Soluble Salts Using Insoluble Reactants

The video tutorial explains how to prepare soluble salts using insoluble reactants like zinc oxide. It outlines the process of adding excess base to react with acid, filtering out insoluble reactants, and evaporating water to obtain pure salt crystals. The technique is applicable to various insoluble reactants, including metals and metal carbonates.

What happens when the solution reaches the point of saturation during the evaporation process?
