Question
The following questions refer to the titration of formic acid,a monobasic, weak acid. The Ka for formic acid is1.7x10-4. Suppose that 25.00 mL of 0.1000 M formic acidare titrated with 0.1000 M NaOH. Kw = 1.0x10-14. a) What will be the initial pH of the solution in the flaskbefore any NaOH has been added? b) What will be the pH of the tirated solution after theaddition of 23.50 mL of NaOH? c) What will be the pH of the tirated solution at theequivalence point?

I found out a) 2.38 and b) 4.96 but I have no idea how to get the equivalence point for c) whichshould be 12.10, can someone please help explain.
