Give a balanced equation for:

Manufacture of sulphuric acid by the - contact process.

Open in App

Solution

The manufacture of sulphuric acid by contact process:

Sulphur is heated in the presence of oxygen to form sulphur dioxide.

$S + O_{2} \to S O_{2}$

Catalytic oxidation of sulphur dioxide gives sulphur trioxide.

$2 S O_{2} + O_{2} \begin{matrix} V_{2} O_{5} ⇌ 450^{\circ} C \end{matrix} 2 S O_{3}$

Sulphur trioxide gas is dissolved in sulphuric acid to form oleum $(H_{2} S_{2} O_{7}) .$

$S O_{3} + H_{2} S O_{4} \to H_{2} S_{2} O_{7}$

Oleum is diluted with water to form sulphuric acid.

$H_{2} S_{2} O_{7} + H_{2} O \to 2 H_{2} S O_{4}$
