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

Question

Quizplus · Accepted Answer

When solutions of sodium sulfate and nickel (II) nitrate are mixed together, they form a precipitate of nickel (II) sulfate. However, when ammonium carbonate is added to the mixture, it reacts with the nickel (II) sulfate to form nickel (II) carbonate, which is insoluble and thus forms a precipitate. Therefore, the precipitate that forms is nickel (II) carbonate.
