Question

In a laboratory experiment a compound X was heated ,it changes its colour into off white after losing its water of crystalization .a. identify the X Compound and write its chemical formula .b. what is blue vitriol

Answer 1

Answer:

X is FeSO4 or Ferrous Sulphate. In the above experiment we have to consider FeSO4.7H2O

Blue Vitrol is the common name for copper sulphate or CuSO4

Answer 2

(a). X is CuSO$_{4}$ commonly known as anhydrous copper sulfate.

(b). CuSO4$_{4}$.5H$_{2}$O commonly known as copper sulfate is known as blue vitriol due to its blue colour.

• Hydrated copper sulfate ( CuSO4$_{4}$.5H$_{2}$O )  is blue in colour whereas anhydrous copper sulfate ( CuSO$_{4}$ ) is white in colour.
• It is used as a fungicide and also in the test for anemia.
