Give balanced equations for the synthesis of an acid from sulphur dioxide gas.

Open in App

Solution

Sulphuric acid can be prepared from sulphur dioxide either by parring the gas through a stream of water or heating it in presence of $V_{2} O_{5}$ and concentrated $H_{2} S O_{4}$ (also known as the contact tower process)

1. $S O_{2} + H_{2} O \to H_{2} S O_{4}$

2. $S O_{2} + \frac{1}{2} O_{2} V_{2} O_{5} - -- \to S O_{3} H_{2} S O_{4} - --- \to H_{2} S_{2} O_{7} H_{2} O - - \to 2 H_{2} S O_{4}$
