Calculate the pH of a 0.250 M solution of a sodium salt, NaA. pKa HA = 4.66
Since only salt NaA and H2O present in the solution so H+ ion comes from hydrolysis of NaA to give NaOH and HA and dissociation of H2O. Hence we calculate pH by formula for salt formed by weak acid and strong base.
A 0.085 M solution of phenylacetic acid (HPac) has a pH of 2.68. Calculate the Ka value of this acid based on the equation: HPAC (aq) + H20 (1) - PAC (aq) + H30+ (aq) Ka *10^
