It is obvious that silver chloride is not very soluble in water. The solubility of AgCl, silver chloride, in water at 20 oC is 0.018 g AgCl/100 mL H 2O. Sodium chloride is readily soluble in water.
The solubility of sodium chloride is 36.0 g NaCl/100 g H 2O. For example, 36 grams of sodium chloride can be dissolved in 100 grams of water at 20 oC. Many ionic compounds are soluble in water and others are not soluble in water. Other names for precipitation reactions include:īefore we discuss precipitation reactions, we will talk about solubility of ionic compounds in water. In this guide, we will learn how to predict the products of a precipitation reaction. A precipitation reaction is a reaction where aqueous solutions of soluble ionic compounds (salts), when mixed, produce an insoluble product called a precipitate.
