Part D- Double Replacement Reactions: In this section, it is important to observe the mixtures you make very carefully. You are looking for the formation of either a precipitate or a gas. If the mixture gets cloudy, that is an indication that a precipitate has formed. 1) Get two medium test tubes. Into one, place about 2 mL of a solution of barium chloride. Into the other add about 2 mL of copper(II) sulfate solution. Note the appearances of the two solutions and then mix them together noting any changes that have taken place.

4. A student has an unknown solution. She knows that the solution could be NaCl(aq), Mg(NO3)2(aq) or Ca(NO3)2. When a solution of silver nitrate was added to her unknown, there was no reaction. When a solution of sodium sulfate was added to her unknown, a white precipitate appeared. What is her solution? Explain your reasoning and write the molecular equation for the reaction that produced the precipitate.
