Prepare a list of the cations involved in this experiment that could not be present in a solution if
carbonate ions, CO3²-, were also present in that solution.
a.
b. Some cations listed in this experiment are not stable in water. They may react with OH-in water to
form H* and an insoluble hydroxide. How would you keep such an insoluble hydroxide from
forming?

scheme for identifying each anion. Draw a flowchart for the identification if possible.
2. Review relevant class materials and answer the following questions:
You are given a solution that may be either NaCl(aq) or Na₂CO3(aq). Present a scheme to find which
substance was present in the solution.
b. Complete and balance the following equations and explain your results.
