Why sodium metal is kept stored in kerosene oil?
> Sodium is kept in kerosene because it is a highly reactive metal. Kerosene oil does not react with sodium and acts as a barrier which restricts its reaction with oxygen and moisture.
Why are sodium and potassium kept in kerosene oil?
Hint: Sodium and potassium are highly reactive metals. They react vigorously with air and water. A large amount of heat is produced in their reaction. To avoid such accidents these metals are kept immersed in kerosene oil.
Why kerosene does not react with sodium?
Sodium is a very reactive element, it is a strong reducing agent therefore it reduces oxygen and water. Compounds present in kerosene are already reduced hence no further reduction of kerosene oil can take place. Therefore Na does not show any reaction with kerosene oil.
Why sodium is stored in kerosene oil and not in h2o?
In the presence of ordinary air, sodium reacts with water to produce a film of sodium hydroxide that fastly absorbs carbon dioxide and produces sodium bicarbonate. The density of sodium is higher than that of kerosene and it does not react with kerosene. Hence, we can store sodium in kerosene but not in water.
Why is sodium stored in kerosene and not in water?
Complete answer: We know that sodium is highly reactive metal. It reacts with oxygen present in the air to produce sodium oxide at room temperature. The density of sodium is higher than that of kerosene and it does not react with kerosene. Hence, we can store sodium in kerosene but not in water.
Why is lithium kept under kerosene oil?
Lithium metal because of low density is a light metal and therefore floats on the surface of the kerosene oil. To prevent its contact with air, it is kept wrapped in paraffin wax.
Why is it stored in kerosene?
Answer: Sodium is stored in kerosene as it is a highly reactive metal. If it is kept in the open air, it easily reacts with the oxygen and catches fire. Since kerosene is a mixture of hydrocarbons, it won’t react with it.
Why is sodium not kept at room temperature?
We have to keep sodium under kerosene to avoid the reaction of sodium with oxygen, carbon dioxide, and moisture. When sodium reacts with water and oxygen a huge amount of heat is generated during this reaction.
Why is it suggested to store sodium in kerosene rather than keeping it in a glass bottle filled with air or water?
Explanation. Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn’t react with kerosene.
Which metal is stored in kerosene?
Sodium
Sodium is stored in kerosene as it is a highly reactive metal. If it is kept in the open air, it easily reacts with the oxygen and catches fire. Since kerosene is a mixture of hydrocarbons, it won’t react with it.
Why metals like Na and K are stored under oil?
Sodium potassium and lithium are stored under oil to prevent their reaction with oxygen moisture and carbon dioxide of air so as to protect them as they are highly reactive metals.
Why is sodium kept under water?
sodium is highly reactive metal and it easily and quickly reacts with water and atmospheric air. If we keep it open in air, it will have a tendency to catch fire very fast. Phosphorus is also very reactive that’s why it is kept in water to prevent it from undergoing reaction with air.
