प्रश्न
Calcium oxide and phosphorous pentoxide are very good drying agents but they are not used to dry HCI gas. Give reasons for each.
उत्तर
Calcium oxide and phosphorous pentoxide are very good drying agents but they are not used to dry HCI gas because they react with hydrogen chloride.
Cao +2HCI → CaCl2 +H2O
2P2O5 + 3HCl → POCl3 + 3HPO3
