Dehydrating agents are substances that have the ability to remove water from other substances. They are commonly used in chemical reactions where the removal of water is necessary. In the given options, the substances that can act as dehydrating agents are:
a) P4O10 (Phosphorus pentoxide):
- Phosphorus pentoxide is a powerful dehydrating agent.
- It reacts vigorously with water to form phosphoric acid, removing water from the system.
- The chemical reaction is as follows: P4O10 + 6H2O → 4H3PO4
b) POCI3 (Phosphorus trichloride):
- Phosphorus trichloride is also a dehydrating agent.
- It reacts with water to form phosphorous acid, removing water from the system.
- The chemical reaction is as follows: POCI3 + 3H2O → H3PO3 + 3HCl
c) Cone.H2SO4 (Concentrated sulfuric acid):
- Concentrated sulfuric acid is a highly effective dehydrating agent.
- It has a strong affinity for water and can remove water molecules from other substances.
- Sulfuric acid reacts with water to release a large amount of heat, which is an indication of its dehydrating properties.
d) P4O6 (Phosphorus trioxide):
- Phosphorus trioxide is not a dehydrating agent.
- It is a reducing agent and reacts with water to form phosphorous acid (H3PO3), not removing water from the system.
Therefore, the correct options are a) P4O10, b) POCI3, and c) Cone.H2SO4, as they can act as dehydrating agents by removing water from other substances.
a) P4O10 (Phosphorus pentoxide):
- Phosphorus pentoxide is a powerful dehydrating agent.
- It reacts vigorously with water to form phosphoric acid, removing water from the system.
- The chemical reaction is as follows: P4O10 + 6H2O → 4H3PO4
b) POCI3 (Phosphorus trichloride):
- Phosphorus trichloride is also a dehydrating agent.
- It reacts with water to form phosphorous acid, removing water from the system.
- The chemical reaction is as follows: POCI3 + 3H2O → H3PO3 + 3HCl
c) Cone.H2SO4 (Concentrated sulfuric acid):
- Concentrated sulfuric acid is a highly effective dehydrating agent.
- It has a strong affinity for water and can remove water molecules from other substances.
- Sulfuric acid reacts with water to release a large amount of heat, which is an indication of its dehydrating properties.
d) P4O6 (Phosphorus trioxide):
- Phosphorus trioxide is not a dehydrating agent.
- It is a reducing agent and reacts with water to form phosphorous acid (H3PO3), not removing water from the system.
Therefore, the correct options are a) P4O10, b) POCI3, and c) Cone.H2SO4, as they can act as dehydrating agents by removing water from other substances.
