Concept:Salt hydrolysis is the reaction between a salt and water that produces an acidic or basic solution.Explanation:When a salt dissolves in water, one of its ions reacts with water molecules.This reaction splits water into H+ and OH− ions.Those ions combine with the salt ion to form an acid or a base.The reaction is limited, so only a weakly acidic or weakly basic solution is produced.This process is known as hydrolysis.Answer:C. Hydrolysis
