A arrow CH 3 COONa arrow Salt (aq. solution basic) B arrow CH 3 COOH / CH 3 COONa arrow pH . of acidic buffer C arrow CH 3 COOH arrow weak acid A > B > C

Q. Consider the following :
A. Sodium acetate
B. Acetic acid + Sodium acetate
C. Acetic acid
The pH of their equimolar aqueous solutions will be such that :

C < B < A

B < A < C

A < B < C

C < A < B

$A \to C H_{3} COON a \to$ Salt (aq. solution basic)
$B \to C H_{3} COO H / C H_{3} COON a$
$\to p H .$ of acidic buffer
$C \to C H_{3} COO H \to$ weak acid
$A > B > C$
