Expert Answer

Step 1

The acid can be represented as HA. Acid dissociation is given. Here, one mole of acid dissociate to form one mole of H+ and one mole of A-.

fullscreen
Step 2

Initial concentration of the acid is 0.095 M. Here 0.13% of this acid gets dissociated. Amount of acid dissociated is calculated. Amount of acid dissociated and the concentration of H+ ion in the aqueous solution is same.

Step 3

pH of the solution can be determined from the concentration of H+ ion in...
