Hints:
The pH of the solution is calculated using the following equations:
(a) Initial conditions (VNaOH = 0), [H] = [HCI]
(b) After initial addition of NaOH and before the end point:
[H]=MCVMNam *V N₂
V LV
(c) At the end point (Vsou 50 mL), all the HCI is being consumed and the acidity
of the solution comes from auto ionization of water which is:
[H]-1×10
