Sodium (Na) reacts very readily with moisture in the atmosphere and turns into its hydroxide (NaOH). This reaction also results in free hydrogen being released, and it is exothermic as well; this generally results in a fire if there are sufficient quantities.
Hence, Sodium is usually preserved in kerosene or in other mineral oils.
Note: Large blocks of Sodium needn't be stored under kerosene. Why? Because the outermost molecules of Na that have already reacted with any available moisture would've formed a protective layer of NaOH, shielding the inner molecules.

How kerosene keep sodium from reacting with air?
Oxygen (which react with sodium) is not dissolved in kerosene.
Why is sodium preserved in kerosene?
Sodium is preserved in kerosene because kerosene is a non-reactive liquid that helps prevent sodium from reacting with moisture or oxygen in the air. This prevents the formation of sodium oxide or sodium hydroxide, which can make the sodium less effective for certain applications. Additionally, storing sodium in kerosene can help prevent it from catching fire, as kerosene is a flammable liquid that can act as a fire suppressant.
Why do sodium kept immersed in kerosene oil do not burn?
Sodium reacts violently with water, releasing hydrogen gas and forming sodium hydroxide. When sodium is kept immersed in kerosene oil, it is isolated from water, preventing the reaction from occurring. Kerosene oil acts as a barrier to keep oxygen away from the sodium, further preventing combustion.
Why sodium is stored in kerosene or paraffin?
Sodium is stored in kerosene or paraffin because these substances are non-reactive towards sodium. Sodium is highly reactive with air and moisture, which can lead to rapid oxidation and potential ignition. Storing sodium in kerosene or paraffin helps to protect it from reacting with these elements.
Why do sodium is stored in kerosene?
because its stupid
Why sodium chloride not kept under kerosene?
It is not necessary; sodium chloride is stable.
Why sodium is stored in kerosene?
Sodium is stored in kerosene because it is highly reactive with air and water. Storing it in kerosene helps prevent it from reacting with moisture and oxygen in the air. This ensures that the sodium remains stable until needed for use.
Which metal is kept immersed in kerosene for storing?
Sodium is a metal that is commonly kept immersed in kerosene for storing because it reacts violently with water and oxygen in the air. Placing it in kerosene helps prevent these reactions and keeps the metal stable.
What chemical will burn violently when mixed with water but not with kerosene?
Sodium and potassium metals will burn violently when mixed with water, forming alkaline hydroxides and hydrogen gas. When mixed with kerosene, a hydrocarbon mixture, the reaction does not occur as kerosene is not reactive with these metals.
Why sodium metal is stored in kerosene?
Sodium is extremely reactive. It oxidizes rapidly in air and reacts violently with water. The kerosene prevents the sodium from coming in contact with air, water, or other substances that might oxidize it.
Why sodium stored in keroseon oil?
when exposed to air or moisture, sodium will catch fire. to prevent that, sodium is stored in kerosene oil
Why do we store sodium metal in kerosene oil not in water?
Sodium metal reacts violently with water, producing hydrogen gas and heat, which can lead to ignition or explosion. Storing sodium in kerosene prevents it from coming into contact with water, reducing the risk of an uncontrollable reaction. Kerosene also forms a protective layer around the sodium, preventing it from reacting with air.
