Question

The oxidizing agent in the equation \[\ce{S + 2H2SO4 -> 3SO2 + 2H2O}\] is ______.

Options

• Sulphur

• Sulphuric acid

• Sulphur dioxide

• Water

Answer 1

The oxidizing agent in the equation \[\ce{S + 2H2SO4 -> 3SO2 + 2H2O}\] is sulphuric acid.

Explanation:

The reaction is as follows:

\[\ce{S + 2H2SO4(conc{.}) -> 3SO2 + 2H2O}\]

The oxidizing agent in this process is concentrated \[\ce{H2SO4}\]. While being converted to \[\ce{SO2}\], it oxidizes sulphur \[\ce{(S)}\] to produce sulphur dioxide \[\ce{SO2}\].
