is cuno3 soluble
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.
