$BaCl_2$

Vedclass · Answer

(A) $BaCl_2$ is a salt of a strong acid $(HCl)$ and a strong base $(Ba(OH)_2)$. Therefore,its aqueous solution is neutral with a $pH$ of $7$. $AlCl_3$,$LiCl$,and $BeCl_2$ undergo cationic hydrolysis in water to produce acidic solutions because they involve weak bases or small,highly charged cations. Consequently,their $pH$ values are less than $7$. Thus,the $pH$ value is highest for the solution of $BaCl_2$.
