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.
