\(C_{12}H_{22}O_{11(s)} + H_2SO_{4(aq)} → 12C(s) + 11H_2O(l) + H_2SO_{4(aq)}\)
In the reaction above, tetraoxosulphate (VI) acid function as

  • A dehydrating agent checkmark
  • An oxidizing agent
  • A reducing agent
  • A catalyst

The correct answer is: A

Explanation

A dehydrating agent is a substance that dries or removes water from a substance.

so when sulphuric acid with sugar, the sugar is charred by the removal of water,  \(C_{12}H_{22}O_{11(s)} + H_2SO_{4(aq)} → 12C(s) + 11H_2O_{(l}) + H_2SO_{4(aq)}\)

the sulphuric acid is serving as a dehydrating agent.

 

There is an explanation video available .
