Question

What can you predict about the solubility of other compounds based on the trends observed above? Make observations of all the possible cation/anion combinations, remembering that clarity of language reduces confusion in communicating your observations. Note specifically that "clear" and "colorless" have two distinct meanings. After you have devised solubility rules, you will predict and then test the behavior of additional ion combinations supplied by your instructor. Correctly name all of the ionic compounds listed above as the anion and cation sources.

Explanation / Answer

Salts constituting Na+ as cation are soluble in water. The list of anion sources mentioned in above list contain sodium as cation, thus they are soluble.

Salts constituing NO3- as anion are soluble in water. The list of cation sources mentioned in above list contain nitrate as anion, thus they are soluble.

NaCl - Sodium Chloride

NaI - Sodium Iodide

Na2SO4 - Sodium Sulphate

Na2CO3 - Sodium Carbonate

NaOH - Sodium Hydroxide

Na3PO4 - Sodium Phosphate

NH4NO3 - Ammonium Nitrate

AgNO3 - Silver Nitrate

Ba(NO3)2 - Barium Nitrate

Sr(NO3)2 - Strontium Nitrate

Pb(NO3)2 - Lead Nitrate

KNO3 - Potassium Nitrate

Ni(NO3)2 - Nickel Nitrate

Cu(NO3)2 - Cupric Nitrate
