Chapter 4, Problem 36E

Calcium cyclamate $\text{Ca}{\left({\text{C}}_{\text{6}}{\text{H}}_{\text{11}}{\text{NHSO}}_{\text{3}}\right)}_{\text{2}}$ is an artificial sweetener used in many countries around the world but is banned in the United States. It can be purified industrially by converting it to the barium salt through reaction of the acid ${\text{C}}_{\text{6}}{\text{H}}_{\text{11}}{\text{NHSO}}_{\text{3}}\text{H}$ with barium carbonate, treatment with sulfuric acid (barium sulfate is very insoluble), and then neutralization with calcium hydroxide. Write the balanced equations for these reactions.
