Concept explainers
(a)
Interpretation:
The original concentration of the given bases whose aqueous solutions has pH 12.24 at
Concept Information:
Strong bases:
Strong bases are formed from alkali metals and alkaline earth metals of Group IA and IIA respectively.
Strong base dissociates into its constituent ions.
For Group IA metal hydroxides, the hydroxide ion concentration is simply the initial concentration of the strong base
For Group IIA metal hydroxides, the hydroxide ion concentration at equilibrium will be twice that of the initial concentration of strong base
pOH definition:
The
On rearranging, the concentration of hydroxide ion
Relationship between
The relationship between the hydronium ion concentration and the hydroxide ion concentration is given by the equation,
As
To Calculate: The original concentration of base
