Answer: Solubility of NaOH is greater and there are more OH- ions in solution.
Explanation: Reactions : NaOH (s) ⇒ Na+ (aq) + OH- (aq)
Mg(OH)2 (s) ⇒ Mg2+ (aq) + 2 OH-(aq)
Although in same amount of moles, Mg(OH)2 produces
two (OH-)-ions in water solution, solubility of Mq(OH)2 is smaller.
Concentration [OH-]ions is smaller in saturated water solution
of Mg(OH)2
