In which pair of ions both produce precipitate with dil. HCl solution :-

Options:(select one or more)

Answer:

B, D

Solution:

The ions in this group are Silver ( $A g^{+}$ ), Lead ( $P b^{2 +}$ ), and Mercurous ( $H g_{2}^{2 +}$ ). They react with dilute HCl to form white precipitates: AgCl, $P b C l_{2}$ , and $H g_{2} C l_{2}$ . Ions like $H g^{2 +}$ and $C u^{2 +}$ belong to Group II and do not form precipitates with HCl alone. Thus, pairs in options (B) and (D) both produce precipitates.
