Consider the following salts: and . Identify the correct set of insoluble salts

Consider the following salts: \( N a C l, H g C l_{2}, H g_{2} C l_{2}, C u C l_{2}, C u C l \) and \( A g C l \). Identify the correct set of insoluble salts in water.

  • A. \( H g_{2} C l_{2}, C u C l, A g C l \)
  • B. \( H g C l_{2}, C u C l, A g C l \)
  • C. \( H g_{2} C l_{2}, C u C l_{2}, A g C l \)
  • D. \( H g_{2} C l_{2}, C u C l, N a C l \)

Step-by-step solution

Based on solubility rules, chlorides are generally soluble except with Ag+, Pb2+, and Hg2^2+ (Hg2Cl2 is insoluble). CuCl is sparingly soluble (considered insoluble in many contexts), while NaCl, HgCl2, CuCl2 are soluble. Thus, the insoluble set is Hg2Cl2, CuCl, and AgCl.
