Is ZnSO4 Colourless?

Anhydrous zinc sulfate is a colorless crystalline solid. 6H2O, and as a heptahydrate ZnSO4. 7H2O. All forms are soluble in water.

Why did the blue solution turn Colourless when zinc was added to copper sulphate?

EXPLANATION: When the Zinc plate is put in Copper sulfate solution, a displacement reaction takes place. Zinc displaces Copper in the Copper sulfate and turns the blue colored solution into colorless.

What colour is ZnSO4 solution?

The color of FeSO4 is green and the color of ZnSo4 is white.

What is the color of CuSO4?

blue
A copper sulphate solution is blue or bluish – green in color. Copper sulphate has also been called blue vitriol, blue – stone and roman vitriol.

What is the colour of cucl2?

Copper chloride appears as a yellowish-brown powder (the anhydrous form) or a green crystalline solid (the dihydrate).

What happens when Zn reacts with CuSO4?

on adding zinc to CuSO4 solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution. This is indicated by colour change from blue to colourless. Zn(s) + CuSO4(aq) -> Cu(s) + ZnSO4 (aq)….

What happens when zinc dust is added to CuSO4?

Complete answer: On adding zinc to copper sulphate solution, zinc displaces copper from copper sulphate and forms zinc sulphate solution. It will undergo a redox reaction, called the displacement reaction of metal because zinc is more reactive than copper according to the reactivity series.

What color is CuSO4?

Cupric sulfate, CuSO4, commonly known as blue vitriol, is the most important salt of copper. It usually crystallizes as CuSO4 · 5H2O and has a bright blue colour. It is prepared by the treatment of copper oxides with sulfuric acid. While readily soluble in water,…

How do you explain the fact that FeSO4 is light green but ZnSO4 is Colourless?

Explanation: In FeSO4 ( Oxidation state of iron is +2), iron has unpaired electrons in its d-subshell, which absorb visible light and imparts colour. In ZnSO4 (oxidation state of Zinc is +2), zinc has all paired electrons in its d-subshell.

What is the difference between CuSO4 and ZnSO4?

Explain the CuSO4 . 5H2O is blue but ZnSO4 .7H2O is colourless. Explain the CuSO4 . 5H2O is blue but ZnSO4 .7H2O is colourless. Please log in or register to add a comment.

Why is CuSO4 blue in colour but CuSO4 is white?

CuSO4.5H2O gives [Cu (H2O)4]+2 ion which is blue in colour. That is why CuSO4.5H2O is coloured but CuSO4 is colourless or can be said white due to lack of water molecule. It absorbs moisture and turn blue in colour.

Why d-d transition is not possible in anhydrous CuSO4?

Best answer In CuSO4.5H2O, water acts as ligandas a resultit causes crystal field splitting. Hence d—d transition is possible in CuSO4.5H2O and shows colour. In the anhydrous CuSO4due to the absence of water (ligand), crystal field splitting is not possible and hence no colour.

Why 2nd complex has no colour?

In case first complex d-d transition is possible but in second complex d-d transition is not possible thats why second complex has no colour
