Ph of alkalis
Did you know?
WebbNot all bases are alkali but all alkali is base. It is a basic salt alkali earth metal or alkali metal. On adding alkali to acid the pH of the mixture increase. On adding acid to alkali the pH decreases due to the removal of alkali. Neutralization is a reaction in which removal of alkalinity or acidity occurs. WebbThe pH scale, from 0 to 14, is a measure of the acidity or alkalinity of a solution, and can be measured using universal indicator or a pH probe. A solution with pH 7 is neutral. Aqueous solutions of acids have pH values of less than 7 and aqueous solutions of alkalis have pH values greater than 7.
