Sodium is not generally "extracted from its ore" to be recovered and used. Most of the sodium we consume is used in the form of sodium compounds, like table salt (NaCl, or sodium chloride). Recovering the pure metal takes some doing as it is highly reactive. Sodium metal reacts with the moisture in air, and must be stored below something like kerosene to keep it isolated and in its elemental form. To extract sodium metal, we generally use electrolysis on molten salt (sodium chloride) in what is called a Downs cell. The metal is recovered, cooled and "packaged" to keep it from reacting with anything prior to use. A link can be found below to check facts and learn more.

Why do you prepare lassaigne extract?
lassaigne extractA small piece of sodium is heated gently in an ignition tube till the sodium melts. About 50 to 60 mg of the organic compound is added to this and the tube heated strongly for 2-3 minutes to fuse the material inside it. After cooling, the tube is carefully broken in a china dish containing about 20 to 30 mL of distilled water. The fused material along with the pieces of ignition tube is crushed with the help of a glass rod and the contents of the china dish are boiled for a few minutes. The sodium salts formed in the above reactions (i.e. NaCN, Na2S, NaX or NaSCN) dissolve. Excess of sodium reacts with water to give sodium hydroxide. This alkaline solution is called Lassaigne's extract or sodium extract. The solution is then filtered to remove the insoluble materials and the filtrate is used for making the tests for nitrogen, sulphur and halogens.ReactionsAn organic compound containing C, H, N, S and halogens when fused with sodium metal gives the following reactions.(NaSCN) is formed during fusion, which in the presence of excess sodium forms sodium cyanide and sodium sulphide.Detection of nitrogenA small quantity of the sodium extract is taken in a test tube. It is made alkaline by adding 2-3 drops of sodium hydroxide (NaOH) solution. 1 mL of freshly prepared solution of ferrous sulphate is added to this solution. The mixture of the two solutions is boiled and then acidified with dilute sulphuric acid. The appearance of prussian blue or green colouration of the precipitate confirms the presence of nitrogen in the given organic compound. The carbon and nitrogen present in the organic compound on fusion with sodium metal give sodium cyanide (NaCN) soluble in water. So, the sodium extract contains sodium cyanide which, on reaction with ferrous sulphate, gives sodium ferrocyanide. Some of the ferrous salt is oxidised to the ferric salt on heating and this reacts with sodium ferrocyanide to form ferric ferrocyanide.Note: When nitrogen and sulphur both are present in any organic compound, sodium thiocyanate is formed during fusion. When extracted with water sodium thiocyanate goes into the sodium extract and gives 'blood red coloration' with ferric ions due to the formation of ferric thiocyanate.Detection of sulphurThe presence of sulphur in any organic compound is detected by using sodium extract as follows:Lead acetate testA small portion of sodium extract is acidified with acetic acid and lead acetate solution is added to it. A black precipitate of lead sulphide indicates the presence of sulphur.Sodium nitroprusside testTo a small quantity of sodium extract taken in a test tube, 2 to 3 drops of sodium nitroprusside are added to the solution. A violet color indicates the presence of sulphur. This color fades away slowly on standing.by: zoren roicres apostol. copy and pastesource:http://www.tutorvista.com.

What is the role of sodium dodecyl sulphate in DNA isolation?
Sodium dodecyl sulphate is a surfactant and functions as a detergent. It solubilizes the lipids present in the cell membrane and internal membrane and components of cell and allows a DNA extract free from lipids which would otherwise be contaminants in biological and biochemical assays.
What is soda extract?
Soda extract for any salt means taking the salt and Sodium Carbonate together in the ratio of 1:4(like one spoonful of salt + 4 spoonful of Na2CO3) and then making their solution in distilled water by completely dissolving them. The resulting solution is your soda extract.
Is sodium chloride an example of a element?
No, that is 2 elements. One element would be Sodium (Na) and another would be Chlorine (Cl). Sodium Chloride would be a compound element.
What are the ingredients of nutrient broth?
peptone, beef extract, yeast extract, sodium chloride peptone, beef extract, yeast extract, sodium chloride
Why would you add carrageenan an extract of Irish Moss or sodium alginate an extract of another seaweed to ice cream?
To keep it from crystallizing
Why you use sodium extract for detection of elements?
we use sodium extract bcz it converts covalent compounds into ionic form..
How are hazards associated with sodium extract preparation controlled?
Acute hazards involved in sodium extract preparation for extra elements detection is eradicated by using NOSIA. The NOSIA stands for nonbreakable sodium ignition apparatus. This apparatus provides a safer technique for sodium extract of the organic compounds.
What is the purpose for producing sodium extract?
hjygtf
Why is aqueous solution sodium extract alkaline?
Because this solution contain sodium hydroxide.
Why distilled water is used to make sodium extract?
because sodium metal immediately react with water and causes explosion thats why we use distilled water in preparing sodium extract by asghar tariq nohri
Ingredients of herbal essences?
There are a number of key ingredients in herbal essences shampoo. These include Water, Sodium Laureth Sulfate, Sodium Lauryl Sulfate, Cocamidopropyl Betaine, Sodium Chloride, Citric Acid, Sodium Citrate, Fragrance, Passiflora Incarnata Flower Extract, Anthemis Nobilis Flower Extract, and Aloe Barbadensis Flower Extract.
What will be the colour of grape extract in aqueous sodium hydroxide?
Violet
Why cant carbon be used to extract sodium from its ore?
because sodium is more reactive than carbon and therefore a displacement reaction cannot take place- which would normally separate sodium from its ore.
Why is sodium difficult to extract?
Sodium is a group one metal which means it is highly reactive. If you have ever seen sodium placed into water you will see it goes off with a bang. The problemm with extracting sodium is water vapor in the air (humidity). Sodium will react with water extreamly easerly and quickly. For that reason it is hard to extract sodium as it reacts with the moisture in the air.
Why is distill water used in sodium extract?
To obtain a purer product.
