Zn gives H2 gas with H2SO4 and HCl but not with HNO3 because

HNO 3 is weaker acid than H 2 SO 4 and HCl

HNO 3 is weaker acid than H 2 SO 4 and HCl

NO 3 – is reduced in preference to hydronium ion

Zn acts as oxidizing agent when reacts with HNO 3

HNO 3 is weaker acid than H 2 SO 4 and HCl

Zinc is present on the top of Hydrogen in electrochemical series, So Zn displaces H₂from dilute H₂SO₄& HCl.

On the other hand ,HNO₃ is an oxidizing agent .Hydrogen obtained in this reaction is converted in to H₂O.
