What is the pH when the solution volume in
the flask reaches 95 ml?
O a 1279
Ob 12.82
OC 1.95
O d. 12.75
De 2.28
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:
MC VC-M NOVNO
[H"]=
V LV
(c) At the end point (Vou 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
(d) After the end point:
1x10-¹4

[H"]=
titrant: NaOH, 0.1M
analyte: HC1, 0.1 M, 50 ml.
