In the titration of 50.00 mL of 1.00 M HC2H3O2 with 1.00 M NaOH, a student was considering using bromcresol as an indicator. Ka HC2H3O2 = 1.8 x 10-5
Kb for C2H3O2-1 = 5.6 x 10-10
(1)How many milliliters of NaOH would it take to reach the endpoint with this titration?
(2)What is the pH of the solution at the end point?
(2)What indicator would be a better choice than bromcresol green for this titration?
