`pH` of a mixture of `1 M` benzoic acid (`pK_(a)=4.20`) and `1 M C_(6)H_(5)COONa` is `4.5`. In `300ml` buffer, benzoic acid is `[log2=0.3]`

1 M benzoic acid (pK_(a)=4.2) and 1 M C_(6)H_(5)COONa solutions are given separately. What is the volume of benzoic acid required to prepare a 93mL buffer solution of pH=4.5 ?

1 M benzoic acid (pK_a=4.20) and 1 M C_6H_5COONa solutions are given separately What is the volume of benzoic acid required to prepare a 300 ml buffer solution of pH =4.5 ? [log 2 =0.3]

100mL of 0.2M benzoic acid (pk_(a)=4.2) is titrated using 0.2 M NaOH pH after 50mL and 100mL of NaOH have been added are :

100 mL of 0.02M benzoic acid (pK_(a)=4.2) is titrated using 0.02 M NaOH . pH values after 50 mL and 100 mL of NaOH have been added are

100 mL of 0.02M benzoic acid (pK_(a)=4.2) is titrated using 0.02 M NaOH . pH values after 50 mL and 100 mL of NaOH have been added are

Fixed volume of 0.1 M benzoic acid (pK_(a)=4.2) solution is added into 0.2 M sodium benzoate solution and formed a 300 mL, resultant acidic buffer solution. If pH of this buffer solution is 4.5 then find added volume of benzoic acid :
