WebThe pH scale measures a solution’s acidity or alkalinity. The range for the pH scale is 0 (strong acid) to 14 (strong alkali). pH 0 – 2: strong acid pH 3 – 6: weak acid pH 7:... WebJan 17, 2024 · The salt ions that react with water may produce either weak acid or weak base or weak acid or weak base. As a result, the \({\rm{pH}}\) of solutions may become less or more than \(7\). This article will learn about salt hydrolysis, hydrolysis constant and determine if the salt is basic, acidic, or neutral.
