Question

For the preparation of the following salts - give a balanced equation in each case.

(iii) Potassium sulphate from KOH solution

Open in App

Solution

When potassium hydroxide (KOH) reacts with sulphuric acid it produces potassium sulphate. This is a neutralization reaction in which base reacts with acids to produce salt and water,

The chemical equation is,

$2 K O H + H_{2} S O_{4} \to K_{2} S O_{4} + 2 H_{2} O$
