Sodium acetate

Vedclass · Answer

(A) The $pH$ of a salt solution depends on the nature of the acid and base from which it is formed.$1$. Sodium acetate $(CH_3COONa)$ is a salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$. It undergoes anionic hydrolysis to form $OH^-$ ions,making the solution basic $(pH > 7)$.$2$. Sodium sulphate $(Na_2SO_4)$ is a salt of a strong acid $(H_2SO_4)$ and a strong base $(NaOH)$. It does not undergo hydrolysis,so the solution is neutral $(pH = 7)$.$3$. Copper sulphate $(CuSO_4)$ is a salt of a strong acid $(H_2SO_4)$ and a weak base $(Cu(OH)_2)$. It undergoes cationic hydrolysis to form $H^+$ ions,making the solution acidic $(pH $4$. Ammonium chloride $(NH_4Cl)$ is a salt of a strong acid $(HCl)$ and a weak base $(NH_4OH)$. It undergoes cationic hydrolysis to form $H^+$ ions,making the solution acidic $(pH < 7)$.

Which among the following salt solutions in water shows a $pH$ greater than $7$?
