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 sodium extract prepared in the detection of hetero elements of an organic compound?
Sodium extract is prepared for the detection of hetero elements in organic compounds because it effectively converts the organic material into soluble sodium salts, facilitating the identification of elements like nitrogen, sulfur, and halogens. The process often involves heating the organic compound with sodium metal, which helps to separate these hetero elements from the organic matrix. This extraction allows for simpler and more reliable qualitative analysis using methods such as color reactions or precipitation tests. Overall, sodium extract enhances the sensitivity and specificity of detecting hetero elements.
How is electrolysis used to extract salt?
Electrolysis is used to extract salt, primarily sodium chloride (NaCl), by dissolving it in water to create a brine solution. When an electric current is passed through the brine, it causes the sodium ions to migrate to the cathode, where they are reduced to form sodium metal, while chlorine ions migrate to the anode, where they are oxidized to produce chlorine gas. This process not only allows for the extraction of sodium but also generates chlorine gas, which is a valuable byproduct. The resulting products can be further processed to obtain pure sodium and chlorine.
Why it is necessary to prepare sodium extract for the detection of foreign elements in organic compounds?
Preparing a sodium extract is essential for detecting foreign elements in organic compounds because it helps to convert the organic material into a soluble form, allowing for easier analysis. The sodium extract facilitates the separation of inorganic ions from the organic matrix, ensuring that the presence of specific foreign elements can be accurately identified. This process also minimizes interference from the organic components, enabling more reliable qualitative and quantitative analysis of the elements of interest.
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.
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.
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
What are the ingredients of nutrient broth?

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.
Why cant carbon be used to extract sodium from its ore?
Carbon cannot be used to extract sodium from its ore because sodium is more reactive than carbon. When carbon reacts with sodium ore, carbon will preferentially react with oxygen in the ore to form carbon dioxide rather than extracting sodium from the ore. Therefore, other methods such as electrolysis are used to extract sodium from its ore.
Why is aqueous solution sodium extract alkaline?
Because this solution contain sodium hydroxide.
Why you use sodium extract for detection of elements?
Sodium extract is commonly used for detecting elements because it has a high sensitivity to the presence of certain metal ions. When a sample is exposed to the sodium extract, emission lines are produced that can be analyzed to determine the elemental composition of the sample. This method is particularly useful in spectroscopic analysis.
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 distilled water is used to make sodium extract?
Distilled water is used to make sodium extract because it is free of impurities and minerals that could interfere with the extraction process. Using distilled water ensures that the extraction of sodium is pure and free from contamination.
Can we use strong solution of NaOH to make sodium extract instead of sodium metal?
No, using a strong solution of NaOH to make sodium extract is not practical due to the high reactivity of sodium with water. Sodium metal is typically produced through electrolysis of molten sodium chloride (NaCl) or other methods that involve isolation of the pure metal.
Why is sodium diffficult to extract?
Sodium is difficult to extract because it is highly reactive with moisture and air, leading to the formation of sodium hydroxide, which can pose safety hazards. Additionally, sodium exists as ions in compounds rather than in its elemental form, requiring energy-intensive processes to separate it from other elements.
What is the purpose for producing sodium extract?
Sodium extract is produced for various industrial applications, such as in the manufacture of detergents, paper, and textiles. It is also used in food processing as a food additive and as a reagent in chemical reactions.
