Vedclass · Answer

(B) The $pH$ at the equivalence point of an acid-base titration depends on the nature of the salt formed.$1$. For a strong acid and strong base,the salt formed is neutral $(pH \approx 7)$.$2$. For a strong acid and weak base,the salt undergoes cationic hydrolysis,resulting in an acidic solution $(pH $3$. For a weak acid and strong base,the salt undergoes anionic hydrolysis,resulting in a basic solution $(pH > 7)$.In the titration of acetic acid ($CH_3COOH$,a weak acid) against sodium hydroxide ($NaOH$,a strong base),the salt formed is sodium acetate $(CH_3COONa)$.$CH_3COO^- + H_2O \rightleftharpoons CH_3COOH + OH^-$The production of $OH^-$ ions makes the solution basic,hence the $pH$ at the equivalence point is greater than $8$.

In which of the following acid-base titrations is the $pH$ at the equivalence point greater than $8$?
