ok I need some time

Explanation:

1. NaOH:Sodium hydroxide is industrially produced using the electrolytic chloralkali process, in which electrolysis of aqueous sodium chloride solution gives chlorine gas and sodium hydroxide. ... Uses: Sodium hydroxide is one of the most widely used bases in industry.
2. CaOH:Preparation of Bleaching Powder. Bleaching powder is synthesized by the action of chlorine gas (produced from the chlor-alkali process) on dry slaked lime (Ca (OH)_2). ...
4. Uses of Bleaching Powder. It is used for bleaching dirty clothes in the laundry, as a bleaching agent for cotton and linen in the textile industry.
6. Baking:Solvay process is used for the production of sodium bicarbonate and sodium carbonate industrially. In this process carbon dioxide, water, ammonia and brine solution in its concentrated form, are used as raw materials. This process is used mainly because it is inexpensive and less number of raw materials are used to produce necessary chemicals. Reduces the acidity in the stomach
8. Acts as an antacid which is used to treat stomach upset and indigestion
10. Used in the process of washing as a water softener
12. Due to the formation of soapy foam, it is used in fire extinguishers
14. washing soda:The four steps involved in the preparation of sodium carbonate are:
16. Purification of Brine
18. Formation of sodium hydrogen carbonate
20. Formation of sodium carbonate
22. Recovery of ammonia.used in the process of softening of water and paper industry.
