Suppose you have an unknown clear, colorless solution. In attempt to identify it, you add NaOH dropwise and find that a white gelatinous precipitate forms, but when more NaOH was added the precipitate dissolved again. To another test tube of the same unknown solution is added AgNO3 dropwise, and a white precipitate forms. What salt most likely comprises the unknown solution? Explain your reasoning (3 points) 2. Suppose you have a different unknown solution that you know to be 50/50 mixture of 2 different 1 M salt chloride solutions. In attempt to identify it, you add sodium hydroxide dropwise, and the solution forms a blue precipitate. Furthermore, upon heating the solution slightly, you notice the solution starting to bubble (below the boiling point water). What are the two likely cations in this unknown solution? Explain your reasoning (3 points).
