Vedclass · Answer

(C) $CH_3COONa$ is a salt of a weak acid $(WA)$ and a strong base $(SB)$,therefore it is alkaline with $pH > 7$ $(A 	o iii)$.$NH_4Cl$ is a salt of a strong acid $(SA)$ and a weak base $(WB)$,therefore it is acidic with $pH $NaNO_3$ is a salt of a strong acid $(SA)$ and a strong base $(SB)$,therefore it is neutral with $pH = 7$ $(C 	o iv)$.$CH_3COONH_4$ is a salt of a weak acid $(WA)$ and a weak base $(WB)$,so its $pH$ depends on the relative values of $pK_a$ and $pK_b$,making it almost neutral $(D 	o i)$.Thus,the correct match is $A 	o iii, B 	o ii, C 	o iv, D 	o i$.

Column $I$	Column $II$
$A$. $CH_3COONa$	$i$. Almost neutral,$pH > 7$ or $< 7$
$B$. $NH_4Cl$	$ii$. Acidic,$pH < 7$
$C$. $NaNO_3$	$iii$. Alkaline,$pH > 7$
$D$. $CH_3COONH_4$	$iv$. Neutral,$pH = 7$

Match the column $I$ with column $II$ and mark the appropriate choice.
