a) For the following chemical reaction, identify the acid, thebase, and the conjugate acid and conjugate base.

H₂O(l) + CH₃COOH(aq) ? CH₃COO^–(aq) + H₃O⁺(aq)

Brønsted-Lowry acid reactant = Select ananswer H2O CH3COOH CH3COO– H3O+ Brønsted-Lowry base reactant = Select ananswer H2O CH3COOH CH3COO– H3O+

CH₃COO^–(aq) is theconjugate Select ananswer acid base of Select ananswer H2O CH3COOH CH3COO– H3O+ .

H₃O⁺(aq) is theconjugate Select ananswer acid base of Select ananswer H2O CH3COOH CH3COO– H3O+ .

b) The equilibrium reaction above lies to theleft. What does this mean in terms of the concentration ofacetic acid (CH₃COOH) relative to the concentration ofacetate (CH₃COO^–)?

CH₃COOH(aq) Select ananswer > (greater than) < (less than) ~(nearly equal to) CH₃COO^–(aq)

c) If HCl was added to the system above (addingH₃O⁺), how would the concentration of aceticacid (CH₃COOH) change?

Acetic acid (CH₃COOH) would Select ananswer Increase Decrease stay thesame .
