Solution
The correct option is C Both a and b
A milky white precipitate was formed when solution containing aluminum cations is treated with ammonium hydroxide. The white precipitate does not dissolve on adding excess ammonia solution. No further reaction is seen on heating. A WHITE ppt was formed on treating cadmium cations with ammonium hydroxide which does not dissolve immediately on adding xs ammonia. No reaction is seen on heating, apart from the formation of a few white ppt. Cadmium Hydroxide was precipitated which formed a complex soluble ion on adding xs ammonia.
