Which of the following statements is/are true for a 0.10 m solution of a weak acid ha? (a) the ph is 1.00 m (b) [h+ ] > > [a - ] (c) [h+ ] = [a -

c. [H+] = [A-]

The dissociation of weak acid in water occurs as shown by the equation;

HA → H+ + A-

The initial concentration of the weak acid is 0.10 M

Since you are dealing with a weak acid, all of it will not be dissociated to free H+.

Equal number of H+ and A- will be formed when HA dissociates. All the molecules will not be dissociated since it is a weak acid.

the answer is 0.8m.
