The ions in sodium chloride salt that undergoes hydrolysis has to be identified. Concept Introduction: Salt hydrolysis: It is the chemical reaction of a salt with water to produce hydronium ion or hydroxide ion or both. Type of salt Nature of aqueous solution strong acid–strong base neutral strong acid–weak base acidic weak acid–strong base basic weak acid–weak base depends on the salt In water, the negative ion of a weak acid or the positive ion of a weak base will undergo hydrolysis (reaction with water).
