0.1 M NaOH is titrated with 0.1 M HA till the end point. K a for HA is 5.6 × 10 –6 and degree of hydrolysis is less compared to 1. Calculate pH of the resulting solution at the end point.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(8.98 ≈ 9)
Sol. HA + OH – 
A – + H 2 O
0.1 V 0.1 V m. moles
– – 0.1 V
[A – ] = 
= 
M,
pH = 7 + 
(pK a + log c) = 7 + 
(6 – log 5.6) + 
log 
= 8.98 ≈ 9
