Why is 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 is sodium 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 is sodium and potassium stored in kerosene not in water 8?

Sodium and potassium are highly reactive metals that react readily with oxygen present in the air. To prevent this reaction they are kept in kerosene.

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 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 are sodium and potassium stored?

Sodium and potassium are stored in kerosene. Sodium and potassium are very reactive metals and readily catches fire in the air. They cannot be kept in water as they react exothermically in water. Therefore they are stored in kerosene.

Why sodium and potassium does not react with kerosene?

We know that sodium is highly reactive metal. It reacts with oxygen present in the air to produce sodium oxide at room temperature. So, it catches fire and begins to burn when it is present in the open air. The density of sodium is higher than that of kerosene and it does not react with kerosene.

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.

Does kerosene contain sodium?

Sodium is the metal stored in kerosene oil in order to prevent it from coming in contact with oxygen and moisture.

Why can sodium and potassium not be stored by immersing them in water?

Answer: Explanation: Sodium and potassium are kept under kerosene because being highly reactive Sodiumand potassium readily react with oxygen present in air it also reacts with water vigorously .

How is potassium stored?

Potassium must always be stored under an inert atmosphere. Even when kept under mineral oil, a yellow coating of potassium superoxide may formafter prolonged storage if oxygen is present in the headspace of the container.

Why can’t sodium and potassium be stored in kerosene?

Sodium and potassium are very reactive metals and readily catches fire in the air. They cannot be kept in water as they react exothermically in water. Therefore they are stored in kerosene. Sodium and potassium are very reactive metal and readily catches fire in the air.

Which of the following metals are stored in kerosene?

Sodium and potassium are stored in kerosene. Sodium and potassium are very reactive metals and readily catches fire in the air. They cannot be kept in water as they react exothermically in water. Therefore they are stored in kerosene.

Why are nna and K kept in kerosene oil?

N a and K are very reactive metals and kept in kerosene oil to prevent it from coming in contact with oxygen and moisture as they react to form their hydroxides. This is an exothermic reaction and lot of heat is generated so both the metals are kept in kerosene oil.

Can sodium and potassium metals react with water?

Expert Answers. Sodium and potassium metals are kept in kerosene or in dry mineral oil. Both of these metals are in Group 1 on the periodic table. All metals in that group are very reactive with water, including moisture in the atmosphere. You may have seen videos where people have thrown chunks of sodium metal into bodies of water.
