Question

What is the effect on the concentration of acetic acid, hydronium ion, and acetate ion when the following are adde to an acidic buffer solution of equal concentrations of acetic acid and sodium acetate: HCl KCH3CO2 NaCl KOH CH3CO2H

Answer 1

a) The concentration CH³OOH

of will increase, the concentration of CH³OO will decrease, and the concentration of H+ will remain unchanged.

b) The concentration of CH³COOH

will increase, while the concentration of H will decrease and the concentration of CH³COOH ions will remain unchanged.

c) There will be no substantial changes in the concentration of any of the species in the reaction.

d) The concentration of CH³COOH will decrease, while the concentration of CH³COO will increase, and the concentration of H+ions will remain unchanged.

e) The concentration of CH³CO²H will somewhat increase, as will the concentrations of H+ and CH³CO².
