Qualitative Analysis

[hasejour96]

Can someone help me figure this one out?

A blue-green solid compound P sparingly dissolves in solution to give a bluish green solution. On adding sodium hydroxide solution there was a pale blue precipitate formed Q that was insoluble in excess. On addition of barium chloride solution there was a white precipitate formed R which dissolved in dilute hydrochloric acid and liberated a gas S which turned calcium hydroxide solution cloudy to form a white precipitate T.

Identify P, Q, R, S and T by writing the chemical formula along with the name. Write all of the ionic equations of the reactions taking place.

Identify P, Q, R, S and T by writing the chemical formula along with the name. Write all of the ionic equations of the reactions taking place.

Here is my guess:
P=CuSO₃
Q=Cu(OH)₂
R=BaSO₃
S=SO₂
T=CaSO₃
