1. If a solution of hydrochloric acid is added to a solution of sodium carbonate, what is observed? Write the net ionic equation of any reaction that may occur (4P). 2. You have a clear colorless unknown solution with a group I cation. After adding some hydrochloric acid solution you obtain a white precipitate. Addition of ammonia causes the white precipitate to dissolve. Acidifying with nitric acid makes the precipitate reappear. Which cation do you suggest was in the unknown...

Report Questions 1. Approximately 1 mL of two clear, colorless solutions-0.1 M Ba(NO3)2and 0.1 M Na2SO4- were combined. Upon mixing, a thick, milky white precipitate formed. After centrifugation, the solution above the precipitate was found to be clear and colorless. Based on these observations, determine if a reaction occurred. If so, write the balanced chemical equation and net ionic equation for the reaction. 2. Predict if a reaction would occur when solutions of 0.1 M Al(NO3)2and 0.1 M KI are combined. Explain...

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.
