Question

Give the equation for :

Heat on sulphur with conc. sulphuric acid

Answer 1

• The equation is -

$S+2H_{2}S{O}_4\to 3S{O}_2+2H_{2}O$

Heating on sulphur with conc. sulphuric acid produces sulphur dioxide and water. This reaction is an oxidation reaction where $H_{2}S{O}_4$ is an oxidizing agent and sulphur $\left(S\right)$ is oxidized to sulphur dioxide.
