Problem- Consider the titration of a 23.0?mL sample of 0.110M HC2H3O2 with 0.120M NaOH. Determine each of the following.
1) The volume of added base required to reach the equivalence point
2) The pH at 4.00mL of added base
Express your answer using two decimal places.
3) The pH at one-half of the equivalence point
4) The pH at the equivalence point
Please define why you think that's the right answer
