what is washing soda?

what is bleaching powder?

 

Bleaching powder:

Chlorine gas obtained in the electrolysis is used for the manufacture of bleaching powder. Chlorine gas on reacting with dry slaked lime [Ca(OH)₂] produces bleaching powder (CaOCl₂). The chemical equation involved in the reaction can be represented as:

Bleaching powder is used for disinfecting water to make it germ-free. It is used in the textile industry to produce cotton and linen materials. It is also used as an oxidizing agent in many chemical industries.

Baking soda:

We know that baking soda is most commonly used in the kitchen for making delicious pakoras. The chemical name of baking soda is sodium hydrogen carbonate (NaHCO₃). Baking soda is produced by using sodium chloride as one of the raw materials. The chemical equation can be represented as follows:

Do You Know:

Sodium hydrogen carbonate is used as an ingredient in antacids. It is alkaline in nature. Hence, it neutralizes excess acid in the stomach and provides relief.

Sodium hydrogen carbonate is also used in soda acid fire extinguishers. It is also used for cooking and sometimes, it is added for faster cooking. The following reaction takes place when it is heated during cooking:

Washing soda:

Washing soda is also produced from common salt. The chemical name of washing soda is hydrated sodium carbonate and its chemical formula is Na₂CO₃.10H₂O. It is obtained by heating sodium hydrogen carbonate.

The re-crystallization of sodium carbonate produces washing soda.

Sodium carbonate is used in the manufacturing of glass, soap, and paper. It is also used for the manufacturing of borax, for removing permanent hardness of water.
