Describe the industrial method for the preparation of sodium Carbonate and its uses
Answers
Explanation:
hope it help you this is the answer of the question
Answer:
Washing Soda is sodium carbonate containing 10 molecules of water of crystallisation. So, we can say that washing soda is sodium carbonate decahydrate (Na2CO3.10H2O).
The sodium carbonate which does not contain any water of crystallisation is called anhydrous sodium carbonateor soda ash (Na2CO3).
Washing Soda is a transparent crystalline solid.
- It is one of the few metal carbonates which are soluble in water.
- Do you know that the solution of washing soda in water is alkaline which turns red litmus to blue.
- Washing Soda has detergent or cleansing properties because it can remove dirt and grease from dirty clothes. Washing soda attacks dirt and grease to form water soluble products, which are then washed away on rinsing with water.
- It has a melting point of 8510C
Washing Soda is used as cleansing agent for domestic purposes like washing clothes. In fact sodium carbonate is a component of many dry soap powders.
- It is used for removing permanent hardness of water.
- It is used in the manufacture of glass, soap and paper.
- It is used in the manufacture of sodium compounds like borax.
- It is the most important agent in laundries.
- It is used in paper, textile, soap, and detergent industries.
Therefore, we can say that washing soda is sodium carbonate with 10 molecules of water which is mainly used as a cleansing agent.
