| Which one of the following statements is correct ?
A. Iron sulphate and copper sulphate crystals have same number of water of crystallization
B. Iron sulphate and zinc sulphate crystals have same number of water of crystallization
C. Zinc sulphate and copper sulphate crystals have same number of water of crystallization
D. Iron sulphate, copper sulphate and zinc sulphate crystals each have same number of water of crystallization
Please scroll down to see the correct answer and solution guide.
Right Answer is: B
SOLUTION
Option 2 is the correct answer.
- Copper sulphate- CuSO4 • 5H2O
- Zinc sulphate- ZnSO4.7H2O
- Iron sulphate- FeSO4.7H2O
Both Iron Sulphate and Zinc Sulphate crystals have same number of water of crystallization, i.e.,7. So, option 2 is correct.
Water of crystallization-
- It refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation.
