The pH and pOH of the given aqueous solution at 25 ∘ C has to be calculated Concept Information: 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. pOH : The pOH of a solution is defined as the negative base-10 logarithm of the hydroxide ion [OH - ] concentration. pOH scale is analogous to pH scale. pOH = -log[OH - ] Relationship between pH and pOH : pOH is similar to pH . The only difference is that in pOH the concentration of hydroxide ion is used as a scale while in pH , the concentration of hydronium ion is used. The relationship between the hydronium ion concentration and the hydroxide ion concentration is given by the equation, pH + pOH = 14, at 25 o C As pOH and pH are opposite scale, the total of both has to be equal to 14.
