Vedclass · Answer

(C) The mixture contains a strong acid $(HCl)$ and a neutral salt $(NaCl)$,resulting in an acidic solution with $pH $(B)$ The reaction is $H_2SO_4 + 2NaOH ightarrow Na_2SO_4 + 2H_2O$. Here,$50 \ mL 	imes 0.1 \ M 	imes 2 \ (	ext{for } H^+) = 10 \ mmol$ of $H^+$ and $50 \ mL 	imes 0.2 \ M = 10 \ mmol$ of $OH^-$. This is complete neutralization,resulting in $pH = 7$.$(C)$ The reaction is $CH_3COOH + KOH ightarrow CH_3COOK + H_2O$. This results in the formation of $CH_3COOK$,which is a salt of a weak acid and a strong base. It undergoes anionic hydrolysis,resulting in a basic solution with $pH > 7$.$(D)$ The reaction is $HNO_3 + NH_3 ightarrow NH_4NO_3$. This results in the formation of $NH_4NO_3$,which is a salt of a strong acid and a weak base. It undergoes cationic hydrolysis,resulting in an acidic solution with $pH < 7$.

In which of the following cases,$pH$ is greater than $7$?
