A weak acid dissociates in pure water according to the equilibrium
HACAU + H200 H30+20 + A 9
1. The weak acid, HA, has an acid dissociation constant, Ka=7.2999999999999998x107, is added to
water at a concentration of 0.51000000000000001M. (construct an ICE chart to assist)

a. What is the H30+ concentration in solution?
HAW + H201) + H30+4 + Acam

b. Describe how and why the addition of highly concentrated (not affecting solution volume) HCI
will affect the A- concentration. Justify your answer.
