Question
The pH of the solution obtanied by mixing 10 mL of 10-1 N HCI and 10 mL of 10-1 N NaOH is:
Options
A.8
B.2
C.7
D.None of these
Solution
Meq. of HCI = 10 × 10-1 = 1
Meq. of NaOH = = 10 × 10-1 = 1
Thus both are neutralised and 1 Meq. of NaCI (a salt of strong acid and strong base) which does not hydrolyse and thus pH = 7.
Meq. of NaOH = = 10 × 10-1 = 1
Thus both are neutralised and 1 Meq. of NaCI (a salt of strong acid and strong base) which does not hydrolyse and thus pH = 7.
