Since C6H5CO2H has a Ka value, it’s a weak acid.
Remember that weak acids partially dissociate in water. The dissociation of C6H5CO2H is as follows: C6H5CO2H(aq) + H2O(l) ⇌ H3O+(aq) + C6H5CO2–(aq); Ka = 6.5 × 10–5.
From this, we can construct an ICE table:
Determine the pH of a 0.461 M C6H5CO2H M solution if the Ka of that is 6.5 x 10 to the -5th.
