Which of the following is not correct ?
- A Ammonia is used as refrigerant
- B A mixture of \(\mathrm{Ca}(\mathrm{CN})_2\) and \(\mathrm{C}\) is known as nitrolim
- C A mixture of \(\mathrm{Ca}\left(\mathrm{H}_2 \mathrm{PO}_4\right)_2\) and \(\mathrm{CaSO}_4 \cdot 2 \mathrm{H}_2 \mathrm{O}\) is known as superphosphate of lime
- D Hydrolysis of \(\mathrm{NCl}_3\) gives \(\mathrm{NH}_3\) and \(\mathrm{HOCl}\)
Answer & Solution
Correct Answer
(B) A mixture of \(\mathrm{Ca}(\mathrm{CN})_2\) and \(\mathrm{C}\) is known as nitrolim
Step-by-step Solution
Detailed explanation
A mixture of calcium cyanamide \(\mathrm{CaCN}_2\) and coke (C) is called nitrolim. It is used as it fertilizer and can be prepared by passing nitrogen on \(\mathrm{CaC}_2\).
