Question

1) The titration of a 25.0 mL sample of a base requires 23.6 mL of 0.100 M HCl. What is the concentration of the base assuming that it is mono-protic?2) The titration of a 50.0 mL sample of di-protic acid requires 23.6 mL of 0.100 M NaOH. What is the concentration of the acid?3) In the titration of a 25 mL sample of a 0.110 M solution of formic acid with 0.110 M strong base, what is the pH initially?4) In the titration of a 25 mL sample of a 0.110 M solution of formic acid with 0.110 M strong base, what is the pH at the half-equivalence point?5) In the titration of a 25 mL sample of a 0.110 M solution of formic acid with 0.110 M strong base, what is the pH at the equivalence point?
