The Skin of a red grape is arguably the most important ingredient of red wine. Because the pulp of the grape is colorless, the tannins and color compounds of the skin are necessary to give red wine its beautiful color. The pigment is transferred into the wine when the skins are left with the juice during fermentation.
According to the solubility rules, all silver salts are insoluble in water with the exception of silver nitrate, silver acetate and silver sulfate. Therefore, AgBr will precipitate out. The other compound Mg(NO 3) 2 will remain in solution because all nitrates, (NO 3) - , are soluble in water.ccording to the solubility rules, all silver salts are insoluble in water with the exception of silver nitrate, silver acetate and silver sulfate.

NH4+ or NH3. NH4+ reacts with water to form H3O+ while NH3 reacts with water to form OH-. That makes NH4+ the stronger acid. 4. All salts can be formed from the neutralization reaction between an acid and a base. In a and be the base is NH3 (or NH4OH) and the acid is phosphoric acid (H3PO4). The different salts in a and b are generated by using different amounts of NH3. In c the base would be NH3 and the acid would be sulfuric (H2SO4).
