الإجراء التجريبي
Sodium hydroxide (0.75 mol) was dissolved in water (180 ml) to prepare an aqueous alkaline solution. Separately from this alkaline solution, an aqueous solution of tin chloride and indium chloride was prepared by dissolving indium chloride (III) tetrahydrate (0.067 mol) and tin chloride (IV) pentahydrate (0.007 mol) in water (400 ml). To the former aqueous alkaline solution, was added dropwise the latter aqueous solution of tin chloride and indium chloride to form a precipitate of a hydroxide or a hydrate comprising tin and indium. The pH of the precipitate was 10.2. A suspension of the precipitate was aged at room temperature for 20 hours, and then washed with water until the pH of the precipitate reached 7.6.
