Vedclass · Answer

(B) $NaCl$ is a salt of a strong acid $(HCl)$ and a strong base $(NaOH)$,so its solution is neutral $(pH \approx 7)$.$NH_4Cl$ is a salt of a weak base $(NH_4OH)$ and a strong acid $(HCl)$,so its solution is acidic $(pH $NaHCO_3$ is an acidic salt,making its solution weakly basic.$Na_2CO_3$ is a salt of a strong base $(NaOH)$ and a weak acid $(H_2CO_3)$,which undergoes anionic hydrolysis to produce $OH^-$ ions,making the solution strongly basic $(pH > 7)$.Therefore,$Na_2CO_3$ has the highest $pH$.

The aqueous solution of which of the following will have the highest $pH$?
