Question

A 0.4000M solution of nitric acid is used to titrate 50.00ml of 0.237M barium hydroxide.

A. write a balanced net inoic equation for the reaction during titration.

B. what are the species present at the equivalence point?

C. what volume of nitric acid is required to reach the equivalence point?

D. what is the pH of the solution BEFORE any HNO3 is added?

E.what is the pH of the solution halfway to the equivalence point?

F. What is the pH of the solution at the equivalence point?

Please answer A-F for credit!

Ba(OH)2 + 2 HNO3 ------> Ba(NO3)2 + 2 H2O

Moles of HNO3 = 2 * moles of Ba(OH)2

Volume HNO3 * 0.4 = 2 * 50 * 0.237

Volume = 59.25 ml
