Because it react with H2o and burned and form H2 vigorously. In air trace amount of water present.

Shailendra Kumar said: (Dec 4, 2010)  
Because it has low ignition temperature, even low than room temperature, at room temperature it react with Oxygen.

Namita Pande said: (Oct 14, 2011)  
Sodium oxidized instantly on exposure to air and reacts violently with water, yielding sodium hydroxide and hydrogen gas. Hence it is preserved under kerosene.

Vinesh said: (Nov 3, 2011)  
Why only kerosene but? why not Alcohol?

Ragu said: (Apr 28, 2012)  
Sodium reacts with air and form following reaction

Na+H2O(IN THE PRESENCE OF O2)=NaOH+H2

So avoid raection with H2o & O2 Na kept in kerosene oil.

Vamsi said: (Jun 20, 2012)  
Because it react with H2O and burned and form H2 vigorously. In air trace amount of water present.

Kriti said: (Jul 5, 2012)  
AS sodium is highly reactive, it reacts with oxygen vigorously to form sodium peroxide when exposed to air. Hence it is stored under kerosene.

Mehjabeen Karim said: (Dec 2, 2012)  
Sodium is most reactive element hence it reacts vigorous that's why some traces kept in kerosene.

Vishwanath said: (Jul 2, 2013)  
Because in water it will burst and also it stores in kerosene in glass bottle.

Sushmitha said: (Sep 4, 2013)  
Sodium is the most reactive element and hence it reacts with water it will burst therefore it stores in kerosene in glass bottles.

Priyanshu said: (Feb 18, 2014)  
Sodium is kept in kerosene because it keeps it away from contact with air[oxygen].

Ramya Sree Akshara said: (Feb 24, 2014)  
Sodium is a silvery white metal belonging to Group1 of the Periodic Table, which is the alkali metals group. Sodium is highly reactive. The pure metal is kept under oil or kerosene because it spontaneously ignites in water. It's interesting to note that sodium metal also floats on water!Room temperature sodium metal is soft enough that you can cut it with a butter knife.

Sachin said: (Mar 22, 2014)  
Why only kerosene? & why not in petrol and alcohol?

Yogesh said: (Apr 12, 2014)  
Why sodium metal is not kept in alcohol and petrol?

Einestene said: (Apr 19, 2014)  
To Nullify the nature of sodium temporarily, it will be stored in kerosene.

Jail Singh Behera said: (Jun 8, 2014)  
Why not kept under petrol?

Nanjegowda said: (Jan 5, 2015)  
Why sodium and potassium is not preserving in petrol?

Sushma said: (Jan 28, 2015)  
Why petrol is not used as preserve sodium and potassium?

Arun Kumar said: (Feb 11, 2015)  
Because petrol is dearer, people will drink alcohol. So kerosene.

Tasmiya Shaikh said: (Feb 18, 2015)  
Sodium is a very reactive metal it react vigorously with oxygen. It is dangerous to keep sodium open. So it is kept in kerosene.

Paimon Dkhar said: (Mar 30, 2015)  
In kerosene there is absolute absent of oxygen.

Avadhesh Kumar Patel said: (Apr 25, 2015)  
Because sodium metal has +1 oxidation no due to this it is easily oxidize in air, and make the sodium oxide.

Devendra Kumar said: (Jul 26, 2015)  
Formulas of kerosene is C10H22Na.

Anurag Singh said: (Mar 1, 2016)  
Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide. This is a strongly exothermic reaction, and lot of heat is generated.

Shahid said: (Mar 19, 2016)  
Why sodium is very reactive metal?

Divya said: (Jul 29, 2016)  
Any example of sodium that is kept in kerosene?

Kavya said: (Aug 14, 2016)  
Sodium is a high reactive metal if it is kept it will get burned. Kerosene is the right metal to store it because water is a universal solvent and is used for many purposes, petrol is used in automobiles, alcohol is used for some other purposes so these are not right place to store it.

Chamdan Kumar Sharma said: (Aug 19, 2016)  
Why sodium is stored only in kerosene? Why not petrol?

Nandini Renwal said: (Sep 4, 2016)  
When is so reactive with oxygen in the air, so how can be it be taken out from kerosene to be cut so easily?

Poornashri said: (Dec 25, 2016)  
Because if it is exposed to atmosphere it reacts as it is a highly reactive metal. Therefore it is kept under kerosene.

Souvik said: (Jan 11, 2017)  
Why it is not stored under alcohol?

S.Abishek Christus [Former Young Scientist Of Kap] said: (Jan 25, 2017)  
AWESOME QUESTION!

When sodium reacts with water it separates the hydrogen from water and starts burning. But kerosene did not contain hydrogen. This is the reason why sodium metal is kept under kerosene.

Yash Panchal said: (Mar 7, 2017)  
Why sodium is kept only in kerosene?

Shivani said: (Jun 7, 2017)  
Why sodium burn in water?

Akthar said: (Jun 24, 2017)  
Kerosene is not the right answer.

Atharv said: (Jul 9, 2017)  
Sodium is highly reactive metal so it comes in contact with air quickly & burns vigorously to form it's oxide to prevent its reaction with air moisture & co2 it kept in kerosene.

Arup said: (Nov 7, 2017)

Lokesh said: (Dec 4, 2017)  
Sodium is a non-polar metal so that it dissolves in polar substance like water as kerosene is non-polar liquid it won't react with kerosene so it is stored in kerosene.

Sanidhaya said: (Jan 26, 2018)  
NO Alcohol as -OH, react to form something cant remember it's like CH3CH2OH + 2Na ---> CH3CH2O-Na + H2.

NO petrol or gasoline dry out in few moments.

Lady Presh said: (Feb 21, 2018)  
Sodium is kept in kerosene to prevent it from being oxidized. Why can't it also be stored in petrol or alcohol?

Kabir said: (May 10, 2018)  
What is kerosene?

Swar said: (Feb 19, 2019)  
@Presh.

Petrol is a highly volatile one. So sodium shouldn't be kept under it.

Shruti said: (May 21, 2019)  
Sodium is highly reactive metal. It reacts with water vapour and as a result of it, a large amount of heat is liberated which can lead to a fatal accident. Sodium does not react with kerosene hence it is kept in kerosene.

Sindhu said: (May 19, 2020)  
To avoid the reaction with the oxygen present in air because sodium is a reactive metal so it is not safe to keep sodium in atmosphere so better store in kerosene.
