A buffer is formed by mixing 20.0 g of HC2H3O2, 20.0 g of NaC2H3O2, and enough water to form 2.00 L of solution.

Question

a. Write the net ionic equation for the reaction of the buffer with a few drops of chloric acid.

b. Write the net ionic equation for the reaction of the buffer with a few drops of lithium hydroxide.

Answer 1

a). C₂H₃O₂^-(aq) + H⁺(aq) ==> HC₂H₃O₂

b). HC₂H₃O₂(aq) + OH^-(aq) ==> C₂H₃O₂^-(aq) + H₂O(l)
