Question

Name the gas . Nitric acid bodwins hydloss
12 A passed through copper Sulphate
solution it gives Pale blue Ppt. On
passage of enocess of gas the pale
blue ppt dissolues to give a inky
blue solution​

Answer 1

Answer:

CuSO4​+2NH4​OH→(NH4​)2​SO4​+Cu(OH)2​(pale−blue)

The cation present in solution B is Copper (Cu+2).

The color of solution B is Blue.

The pale blue precipitate of copper hydroxide dissolves in excess of ammonium hydroxide forming tetraamine copper [II] sulphate, an azure blue(deep blue) soluble complex salt.

Cu(OH)2​+(NH4​)2​SO4​+2NH4​OH→[Cu(NH3​)4​]SO4​+4H2​O
