1.	Write balanced equation for the following reactions : An aqueous solution of sodium hydroxide is added dropwise to a solution of gallium chloride in water. A precipitate is formed initially which dissolves on further addition of NaOH solution.
Answer» hydroxide is used to identify the BASIC cation. Sodium hydroxide and GALLIUM chloride are IONIC compounds. When aqueous solutions of these TWO compounds are mixed and if a precipitate is formed it means mutual ion exchange has taken place. If this insoluble substance dissolves on further addition of sodium hydroxide, it means a soluble complex is formed. insoluble soluble
