Soluble – Na + ions and CO 3 2– ions are produced. PROBLEM: Decide if each of the following is water soluble. If soluble, tell what ions are produced. (a) Na 2 CO 3 (b) CuSO 4 (c) NiS (d) BaBr 4. Step 2 : Most salts of sulfates are soluble.

Soluble – Na+ ions and CO32– ions are produced. PROBLEM: Decide if each of the following is water soluble. If soluble, tell what ions are produced.(a) Na2CO3 (b) CuSO4(c) NiS (d) BaBr4 Step 2: Most salts of sulfates are soluble. Soluble – Cu2+ ions and SO42– ions are produced. Step 3: Most salts of sulfides are insoluble (Black smokers are thermal vents) Insoluble Step 4: Salts of halides are mostly soluble Soluble – Ba2+ ions and Br– ions are produced. Step 1: Alkali metal salts tend to be soluble
