A. The carbon dioxide of the atmosphere, being a nonmetallicoxide and acid anhydride, has a low solubility in rainwater butproduces a slightly acidic solution. Write an equilibrium equationfor the dissolution of carbon dioxide in water and identify theacid that it formed.
B. Calcium carbonate, the major component of limestone, isslightly soluble in water. Write an equilibrium equation showing the slight solubility of calcium carbonate in water.
C. Write a Bronsted equation for the weak acid formed in partA, showing how it produce hydronium ion in aqueous solution.
