(C) Both $Pb^{2+}$ and $Ba^{2+}$ ions form yellow precipitates with $K_2CrO_4$ in acetic acid and white precipitates with dilute $H_2SO_4$. However,lead salts $(Pb^{2+})$ form precipitates with $NaCl$ $(PbCl_2)$ or $NaI$ $(PbI_2)$,whereas barium salts $(Ba^{2+})$ do not form precipitates with these reagents. Therefore,the given salt must be a barium salt. When sodium carbonate $(Na_2CO_3)$ is added to a barium salt solution,it forms a white precipitate of barium carbonate $(BaCO_3)$.
