Which one of the following substances is used in the laboratory for a ...
Anhydrous calcium chloride is a substance that is used in the laboratory for the fast drying of neutral gases. Calcium chloride is a hygroscopic substance, which means that it absorbs moisture from the air. When it is placed in a container with a gas, it absorbs any moisture present in the gas, effectively drying the gas.
Calcium chloride is preferred for drying gases in the laboratory because it is effective at drying gases quickly and is relatively inexpensive. It is also relatively non-reactive, making it safe to use with most gases.
Phosphorus pentoxide is a highly reactive compound that is not typically used for drying gases. It is a powerful dehydrating agent that is used in chemical reactions, but it is not suitable for use in drying gases because of its reactivity.
Active charcoal is a form of carbon that is used for a variety of purposes, including the adsorption of gases. However, it is not typically used for drying gases because it is not as effective at removing moisture as other drying agents.
Na3PO4 is a compound of sodium and phosphorus, but it is not typically used for drying gases.

Anhydrous Calcium Chloride for Fast Drying of Neutral Gases
Anhydrous calcium chloride is a commonly used drying agent in the laboratory for the fast drying of neutral gases. This substance has a strong affinity for water molecules and can effectively absorb any moisture present in the gas sample.
Why Anhydrous Calcium Chloride is Used?
Anhydrous calcium chloride is used for fast drying of neutral gases for the following reasons:
1. High Absorption Capacity: Anhydrous calcium chloride has a high absorption capacity for water molecules. It can absorb up to 25% of its weight in water, making it an effective drying agent for neutral gases.
2. Fast Drying: The strong affinity of anhydrous calcium chloride for water molecules ensures fast drying of neutral gases. This is particularly useful in laboratory experiments where time is a critical factor.
3. Cost-Effective: Anhydrous calcium chloride is a cost-effective drying agent compared to other drying agents such as phosphorus pentoxide and molecular sieves.
4. Availability: Anhydrous calcium chloride is readily available in most chemical supply stores, making it a convenient choice for laboratory use.
Conclusion
Anhydrous calcium chloride is a popular choice for fast drying of neutral gases in the laboratory due to its high absorption capacity, fast drying properties, cost-effectiveness, and availability. It is important to note that anhydrous calcium chloride should not be used for drying acidic or basic gases as it can react with these gases and form unwanted by-products.
