6-2.Equilibrium-II (Ionic Equilibrium)
medium
$40\, mL\, 0.1\, M\, NaOH$ સાથે $40\, mL\, 0.1\, M\, CH_3COOH$નું તટસ્થિકરણ કરતાં દ્રાવણની $pH$ શું મળશે?
A
$7$
B
$8$
C
$6$
D
$3$
(AIIMS-2007)
Solution
As $NaOH$ is a strong base and $CH_3COOH$ is a weak acid. So on neutralisation of $40\, mL\, 0.1\, M\, NaOH$ with $40\, mL\, 0.1\, M\, CH_3COOH$, we obtain a basic solution of $pH > 7$. ence, option $(b)$ is correct.
