Calcium cyclamate Ca(C6H11NHSO3)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 C6H11NHSO3H 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.
