1.
Sodium hydroxide solution is added to solution A.
A white precipitate is formed
which is insoluble in excess of Sodium hydroxide solution.
What is the metal ion
present in solution A?
2.
When Ammonium hydroxide solution is added to solution B a pale blue
precipitate is formed.
This pale blue precipitate dissolves in excess of Ammonium
hydroxide giving an inky blue solution.
What is the cation present in solution B?
What is the probable colour of solution B?
