Equimolar solutions of the following substances were prepared separate

1.	Equimolar solutions of the following substances were prepared separately. Which one of these has highest pH value?
Answer» `BaCI_(2)` `AICI_(2)` `LiCI` `BeCI_(2)` Solution :The bases and acids which constitute these salts are: `BaCI_(2) : BA(OH)_(2) +2HCI` `AICI_(3) , AI(OH)_(3) + 3HCI` `LiCI : Li(OH) + HCI` `BeCI_(2) : Be(OH)_(2) + 2HCI` Since `Ba(OH)_(2)` is the strongest base , `BaCI_(2)` solution has the maximum pH VALUE.
