When aqueous solutions of two salts are mixed, the third salt formed may appear as a solid precipitates or a clear solution depending upon the solubility of its ions. It is observed that all salts of Na , K , NH ₄ are soluble. All nitrates and bicarbonates are also soluble. All halides (chlorides, bromides, iodides) are soluble except those of Ag , Hg (I) and Pb . All sulphates are soluble except those of Ag , Ca , B

Options

  1. ASodium sulphate and barium chloride
