4. Imagine that the unknown solution contains aqueous ammonium sulfate, which is commonly used in fertilizer. Write a balanced equation for the precipitation of barium sulfate after mixing aqueous ammonium sulfate and barium chloride.
5. Potassium carbonate is frequently used in the production of cocoa powder, and like sodium bicarbonate, is easily dissolved in water. Write the balanced reaction between potassium carbonate and water to produce carbon dioxide.
6. Identify and discuss any sources of error for this experiment. How could you mitigate error?
