Question : 1
Which of the following elements are contained in the fertilizer super-phosphate?
- Phosphorus
- Hydrogen
- Nitrogen
- Calcium
a) 2, 3 and 4
b) 3 and 4
c) 1, 2 and 4
d) 1, 2 and 3
Answer »Answer: (c)
Superphosphate is made by treating phosphate rock with concentrated H2SO4.
It is Ca(H2PO4)2 and hence contains calcium, hydrogen, and phosphorous according to the oxide formation method.
