MCQ
Ammonia can be dried by
- ACons. $H_2SO_4$
- B$P_4O_{10}$
- ✓$CaO$
- DAnhydrous $CaCl_2$
$\mathrm{CaCl}_{2}+4 \mathrm{NH}_{3} \rightarrow \mathrm{CaCl}_{2} \cdot 4 \mathrm{NH}_{3}$
$\mathrm{P}_{4} \mathrm{O}_{10}$ reacts with $\mathrm{NH}_{3}$ to form ammonium phosphate.
$6 \mathrm{NH}_{3}+\mathrm{P}_{2} \mathrm{O}_{5}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow 2\left(\mathrm{NH}_{4}\right)_{3} \mathrm{PO}_{4}$
The gas is passed through fresh quicklime (solid CaO lumps) to effectively dry it.
