Sodium Dichromate Formula
Sodium Dichromate Formula
The Sodium Dichromate Formula is also known as the Disodium dichromate formula or Bichromate of soda formula and it is this compound that is discussed in the article. Sodium Dichromate Formula is inherently an inorganic compound and it releases extremely toxic fumes of chromium when it is simply heated. Sodium Dichromate Formula is a severely corrosive substance. The compound is an electrovalent compound which means that the compound is formed by having bonds which are formed in the first place by the exchange of electrons. The molecular or chemical formula of Sodium dichromate is Na2Cr2O7.
Structure of Sodium Dichromate:
Sodium Dichromate Formula or Na2Cr2O7 is a compound which is orange to red-coloured and has a crystalline structure, and it is an inorganic compound which releases toxic chromium gases on heating. Sodium Dichromate Formula is a highly corrosive compound in nature and is a very strong oxidizing agent. Sodium Dichromate Formula is normally used to produce other chromium compounds but it can also be used for drilling muds, metal treatments, wood preservatives, production of dyes and organic chemicals, and as a corrosion inhibitor. Students will learn about Sodium Dichromate Formula in detail like the sodium dichromate reaction, sodium dichromate chemical formula, the various kinds of uses, properties, density, and structure.
Preparation of Sodium Dichromate:
Sodium Dichromate Formula can be obtained from particular substances called ores which directly contain chromium (III) oxides.
- The first to make the Sodium Dichromate Formula is a step to fuse the ore with a base such as sodium carbonate.
- a temperature around 1000 °C has to be maintained.
- the above two steps is carried on in the presence of air which is the source of oxygen. The reaction is given below:
2Cr2O3 + 4Na2CO3 + 3O2 —> 4Na2CrO4 + 4CO2
These steps can make the chromium soluble and allow it to be extracted in the hot water. The other components present in the ore are not very soluble and therefore, if the products are acidified of the resulting aqueous extract by utilizing carbon dioxide or sulfuric acid, it greatly helps to produce dichromate. The reaction is as follows:
2Na2CrO4 + 4CO + H2O —> Na2CrO7 + 2NaHCO3
2Na2CrO4 + H2SO4 —> Na2CrO7 + Na2So4 + H2O
Using the process of crystallization, dichromate is extracted as a dihydrate.
Properties Of Sodium dichromate Formula
Sodium Dichromate Formula mainly affects the respiratory system of the person handling it which can cause a bad case of shortness of breath and the condition can worsen by getting asthma. Sodium Dichromate Formula also affects the gastrointestinal tract and in bad conditions, it even affects the immune system. The Sodium Dichromate Formula can cause cancer in people by affecting the lungs.
Physical Properties of Sodium Dichromate
The Sodium Dichromate Formula is a crystalline solid compound which has a hue of orange to red in colour. The Sodium Dichromate Formula is a very strong agent which can cause oxidation and is mostly used to produce various other chromium compounds.
Chemical Properties of Sodium Dichromate
The chemical formula of the substance is Na2Cr2O7
If the Sodium Dichromate Formula is anyhow inhaled or taken in by the body can cause respiratory irritation that can worsen into becoming asthma and nasal septal perforation and people handling the Sodium Dichromate Formula has to be very careful. Swallowing Sodium Dichromate Formula often leads to diarrhoea and sometimes leads to a bad case of vomiting. If the Sodium Dichromate Formula is made to contact the eyes and skin it results in a condition called dermatitis and local irritation.
Sodium dichromate is a compound that cannot simply combust like other substances but increases the combustion of other compounds. Sodium Dichromate Formula can just explode and catch fire whenever it comes in contact with other combustible substances and therefore the Sodium Dichromate Formula must be carefully handled.
Use Of Sodium Dichromate
The primary use of the Sodium Dichromate Formula is to make other chromium products, Sodium Dichromate Formula also has other uses as an ingredient in the production of the following materials:
- The Sodium Dichromate Formula helps against corrosion, making it easier to clean the metallic surfaces of different objects and allowing the paint to stick.
- Sodium Dichromate Formula is used as an oxidiser for the production of vitamin K and different kinds of wax.
- The Sodium Dichromate Formula is used in making different inorganic chromate pigments where it produces a variety of light-stable colours. Some grades of chromate are used so that different objects are not subjected to corrosion in undercoats and primers.
- The Sodium Dichromate Formula is used to produce coloured glass and ceramic glaze.
- Sodium Dichromate Formula can be used as a mordant in dyes that are simply acidic to improve colour-fast properties.
- Sodium Dichromate Formula is used in chromium sulphate production.
