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.
