Question

the calcium present in the____reacts with the water and air to form carbonic acid
O Iimestone
O marble
O granite
O slate​

Answer 1

Answer:

Effect of Limestone

Acids in acid rain promote the dissolution of calcium carbonate by reacting with the carbonate anion. This produces a solution of bicarbonate. Because surface waters are in equilibrium with atmospheric carbon dioxide there is a constant concentration of carbonic acid, H2CO3, in the water.

Explanation:

Carbonic acid, (H2CO3), a compound of the elements hydrogen, carbon, and oxygen. It is formed in small amounts when its anhydride, carbon dioxide (CO2), dissolves in water. HCO3− + OH− ⇌ CO32− + H2O (fast) Between pH values of 8 and 10, all the above equilibrium reactions are significant.
