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.
