Vedclass · Answer

(D) Equimolar solutions of the given alkaline earth metal chlorides in water undergo hydrolysis to form their respective hydroxides.The basic strength of alkaline earth metal hydroxides increases down the group as the metallic character increases and the ionization energy decreases.The order of basic strength is $Mg(OH)_2 Since $Ba(OH)_2$ is the strongest base among the given options,its solution will have the highest concentration of $OH^-$ ions,resulting in the highest $pH$.

$A$. Calcium	$p$. Brick red
$B$. Strontium	$q$. Apple green
$C$. Barium	$r$. Crimson

Equimolar solutions of the following were prepared in water separately. Which one of the solutions will record the highest $pH$?
