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.

(Hint: look at the acids and bases that formed them) For example: KCH 3 COO was formed in the reaction between KOH and CH 3 COOH KOH is a strong base. Its conjugate acid, K + , has negligible acidity and will leave the pH at 7.00, a neutral solution.CH 3 COOH is a weak acid, making its conjugate base, CH 3 COO-a relatively strong base. It will produce a basic solution. a) KF b) KCN basic basic c) NaNO 3 d) RbI neutral neutral e) NH 4 NO 3 f) Na 2 CO 3 acidic basic.Hint: look at the acids and bases that formed them) For example: KCH 3 COO was formed in the reaction between KOH and CH 3 COOH KOH is a strong base.
