Vedclass · Answer

(A) $MgCl_2$ is a salt formed from a strong acid $(HCl)$ and a weak base $(Mg(OH)_2)$.In an aqueous solution,$MgCl_2$ undergoes hydrolysis.The $Mg^{2+}$ ion reacts with water to form $Mg(OH)^+$ and $H^+$ ions.Since $H^+$ ions are produced,the concentration of $H^+$ increases,making the solution acidic.Therefore,the $pH$ of the solution is less than $7$ $(pH < 7)$.

The $pH$ of an aqueous solution of $MgCl_2$ is .......
