Calculate the pOH and pH of the following aqueous solutions at 25°C: (a) 0.016 M KOH, (b) 1.35 M NaOH, (c) 0.094 M Ba(OH)2.
(a)

Interpretation:
The
Concept Information:
Strong acids:
In strong acids, the ionization of acid is complete. This implies that the concentration of the hydrogen ion or hydronium ion will be equal to the initial concentration of the acid at equilibrium.
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
The
Relationship between
The relationship between the hydronium ion concentration and the hydroxide ion concentration is given by the equation,
