Granulated zinc reacts with dilute sulphuric acid to form dihydrogen.
Properties of Dihydrogen: 1) It is colourless, tasteless, odourless gas. 2) It is lighter than air. 3) It is highly combustible. It burns in air with a pale blue flame. 4) It reacts with carbon monoxide at 700 K in the presence of a catalyst Zn/Cr2O3 to form methanol.
