Vedclass · Answer

(A) To arrange the solutions in increasing order of $pH$,we identify the nature of each substance:$1$. $HNO_3$ is a strong acid,so it has the lowest $pH$ (highly acidic).$2$. $NH_4Cl$ is a salt of a strong acid $(HCl)$ and a weak base $(NH_4OH)$,making it acidic $(pH $3$. $KI$ is a salt of a strong acid $(HI)$ and a strong base $(KOH)$,making it neutral $(pH = 7)$.$4$. $CH_3COONa$ is a salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$,making it basic $(pH > 7)$.Comparing these,the order of increasing $pH$ is: $HNO_3 < NH_4Cl < KI < CH_3COONa$.

Arrange the following $1 \ L$ aqueous solutions of equal concentration in increasing order of their $pH$:
$CH_3COONa, KI, NH_4Cl, HNO_3$
