a. Copper II sulfate dissolveds in water to form a blue solution. What species are present in solution, i.e., what is actually swimming around in solution? write the formulas.
b. sodium carbonate dissolves in water to form a colorless solution. What species are present in solution? write the formulas.
c. when solutions of copper II sulfate and sodium carbonate are mixed, blue copper II carbonate precipitates. What species remain in solution? (these are the spectator ions.) what is the color of the solution? [Assume that stoichiometric amounts of copper II sulfate and sodium carbante are mixed.] Write the formulas.
