Write a balanced equation for the reaction that occurs when the hydrogen carbonate ion behaves as a Brønsted-Lowry acid in water. a. HCO3–(aq) + H2O(l) ⇌ H2CO3(aq) + H3O+(aq) b. CO32–(aq) + H2O(l) ⇌ HCO3–(aq) + OH–(aq) c. HCO3–(aq) + H2O(l) ⇌ CO32–(aq) + H3O+(aq) d. HCO3–(aq) + H2O(l) ⇌ H2CO3(aq) + OH–(aq) e. H2CO3(aq) + H2O(l) ⇌ HCO3–(aq) + H3O+(aq)    

Problem

Some polyatomic ions containing hydrogen can act as Brønsted-Lowry acids or bases. Write a balanced equation for the reaction that occurs when the hydrogen carbonate ion behaves as a Brønsted-Lowry acid in water.

a. HCO3(aq) + H2O(l) ⇌ H2CO3(aq) + H3O+(aq)

b. CO32–(aq) + H2O(l) ⇌ HCO3(aq) + OH(aq)

c. HCO3(aq) + H2O(l) ⇌ CO32–(aq) + H3O+(aq)

d. HCO3(aq) + H2O(l) ⇌ H2CO3(aq) + OH(aq)

e. H2CO3(aq) + H2O(l) ⇌ HCO3(aq) + H3O+(aq)
