A 100ml solution of 0.1N HCl was titrated with 0.2N NaOH solution . The titration was discontinued after adding 30ml of NaOH solution . The remaining titration was completed by adding 0.25 N KOH solution . The volume of KOH required for completing the titration is ___ .
(a) 70 ml. (b) 32 ml. (c)35 ml. (d)16ml
0.1M acetic acid solution is titrated aginst 0.1 M NaoH solution. What would be the difference in pH between 1/4 and 3/4 stages of neutralization of acid?
