Saturated aqueous solutions of sodium sulfate,ammonium carbonate,and nickel (II)nitrate are mixed together.The precipitate that forms is ________.

Question

Quizplus · Accepted Answer

When sodium sulfate and nickel (II) nitrate are mixed, no precipitate forms because both salts are soluble in water. However, when ammonium carbonate is added, it reacts with sodium sulfate to form ammonium sulfate and sodium carbonate, both of which are soluble in water. The nickel (II) ion then reacts with carbonate ion to form a solid precipitate of nickel (II) carbonate, which is insoluble in water. Therefore, the answer is A) nickel (II) carbonate.
