Step-by-Step Verified Solution
Equimolar solutions of the given chlorides
when prepared in water forms their respective
hydroxides.
SrCl 2 + 2H 2 O _ Sr(OH) 2 + 2HCl
BaCl 2 + 2H 2 O _ Ba(OH) 2 + 2HCl
MgCl 2 + 2H 2 O _ Mg(OH) 2 + 2HCl
CaCl 2 + 2H 2 O _ Ca(OH) 2 + 2HCl
Be(OH) 2
is amphoteric, but the hydroxides of other
alkaline earth metals are basic. The basic strength
increases down the group. Hence higher the basic
character higher will be the pH.
