When solubility of metal hydroxide in water is high, it gives a good alkaline solution due to complete dissociation of metal hydroxide compound for releasing of hydroxyl ions (OH - ) into the water. (ii) NH4OH Solution when added to the Solution (B) gives white precipitate which does not dissolve in excess. Benzoic acid is a weak acid, thus it will only partially dissolve in water. Although aluminum hydroxide is insoluble in water, sodium hydroxide is very soluble.
