1.	The ion that cannot be precipitated by both HCl and `H_2 S` isA. `Pb^(2+)`B. `Cu^(+)`C. `Ag^(+)`D. `Sn^(2+)`
Answer» `Pb^(2+)` and `Ag^(+)` can be precipitated both by HCl and `H_(2)S` `Cu^(+)` dissolves in conc. HCl but is precipitated on dilution. It is also precipitated by `H_(2)S`. `Sn^(2+)` is not precipitated by HCl. It is precipitated by `H_(2)S` only.
