When the compound, Na2S, is mixed with water, the Na2S is: soluble because all Na+1 compounds are soluble in waterinsoluble because most Na+1 compounds are insoluble in watersoluble because all S−2 compounds are soluble in waterinsoluble because there are no water soluble S−2 compounds. 7. Fam IA cmpds, Ca(OH)2, BaSO4, NH4Br, Li2CO3, CuCl, (NH4)2S, PbI2, SrSO4 Soluble Compounds. Magnesium chloride is also soluble in water like chlorides of most metals. Sulfides are insoluble unless combined with Li, Na, K, Rb, Cs, and NH4. Oxides (O2-) are usually insoluble. All are soluble in water except MgS, magnesium sulphide. Insoluble in ether Alfa Aesar 65122: Experimental Density: 1.856 g/mL Alfa Aesar 65122, 88697: Miscellaneous. Decomposes in acid. soluble because all s−2 compounds are soluble in water. Hydroxides (OH-) are usually insoluble. The catalyst activities for Na2S oxidation in aqueous soln were examined for various materials such as activated C, C black, ferric salts, hydroquinone, 1,4-naphthoquinone-2-sulfonic acid sodium salt, 1,4-naphthoquinone and their mixed systems. MgS (s) + 2H2O (l) = Mg (OH)2 (s) + H2S (g) Sodium salts are generally soluble in water. 1) Na2S (aq) + KCl (aq) 2) Li2S (aq) + Pb(NO3)_2 (aq) 3) Pb(ClO3)_2 (aq) + … In warm water because all sodium compounds are insoluble and NH4 soluble, even though most carbonates insoluble!
