Both dihydrogen and carbon monoxide burn in air with blue flame. How will you distinguish between them?

Text Solution

Verified by Experts

Dihydrogen burns with a blue flame in air to form water vapour which turns white anhydrous CuS`O_(4)` into hydrated copper sulphate (CuS`O_(4)cdot 5H_(2)O`) . However, carbon monoxide on combustion forms `CO_(2)` which does not bring about any change in Cu`SO_(4)`.
