Reactions of Lead (Pb) with cold, dilute acids are very slow. Some examples are as follows:- 1) Reaction with dil. HCl and gives PbCl2 and H2 gas. Pb + 2HCl ---> PbCl2 + H2 Solid Aqs. Aqs. Gas 2) Reaction with dil. H2SO4 and gives PbSO4 and H2 gas. Pb + H2SO4 ----> PbSO4 + H2 Solid Aqs. Aqs. Gas 3) Reaction with dil. HNO3 and gives Pb(NO3)2 and H2 gas. Pb + 2HNO3 ------> Pb(NO3)2 + H2 Solid Aqs. Aqs. Gas Regards- Ashutosh talktomehiya@gmail.com
