Solution: Consider the following reaction: HCO3-(aq) + H2O(l) ⇌ H2CO3(aq) + OH -(aq) Which of the following statements is TRUE? a) HCO3- is not an acid and thus the equation is incorrect. b) The reaction of HCO3- with H2O produces H3O+ rather than OH - c) HCO3- is the base and H2O is the acid. d) HCO3- is the acid and OH - is its conjugate base. e) H2O is the base and H2CO3 is its conjugate acid

Problem

Consider the following reaction:

HCO3-(aq) + H2O(l) ⇌ H2CO3(aq) + OH -(aq)

Which of the following statements is TRUE?

a) HCO3- is not an acid and thus the equation is incorrect.

b) The reaction of HCO3- with H2O produces H3O+ rather than OH -

c) HCO3- is the base and H2O is the acid.

d) HCO3- is the acid and OH - is its conjugate base.

e) H2O is the base and H2CO3 is its conjugate acid
