Stannic oxide when ignited with chlorides is more or less completely converted into stannic chloride, which volatilises.
By adding hydrate of potassium or an alkaline carbonate to a solution of stannic chloride.
Double salts of cerous chloride with stannic chloride, mercuric chloride, and platinic chloride are also known.
Since some stannic chloride will have been lost in the evaporation, a low result may be expected.
What are the products of hydrolysis when stannic chloride is used as a mordant?
