Write the chemical name of Na2CO3.10H2O and Na2CO3. Write the signific

1.	Write the chemical name of Na2CO3.10H2O and Na2CO3. Write the significance of 10H2O. Mention the term used for water molecules attached with a salt. With the help of a chemical equation explain the method of preparation of both Na2CO3.10H2O and Na2CO3. Also list two uses of Na2CO3.10H2O.
Answer» Na₂CO₃.10H₂O - Sodium carbonate decahydrate. Na₂CO₃ - Anhydrous sodium carbonate 10H₂O - Water of crystallization which impacts shape and colour to the crystals. Preparation: NaCl + H₂O + CO₂ + NH₃ → NH₄CI +NaHCO₃ 2NaHCO₃ +Heat→ Na₂CO₃ + H₂O + CO₂ Na₂CO₃ + 10H₂O → Na₂CO₃.10H₂O Uses: (i) Used in glass, soap and paper industries. (ii) Used in the manufacture of borax. (iii) Used as a cleansing agent for domestic Purpose.

Answer»

Na₂CO₃.10H₂O - Sodium carbonate decahydrate.

Na₂CO₃ - Anhydrous sodium carbonate

10H₂O - Water of crystallization which impacts shape and colour to the crystals.

Preparation:

NaCl + H₂O + CO₂ + NH₃ → NH₄CI +NaHCO₃

2NaHCO₃ +Heat→ Na₂CO₃ + H₂O + CO₂

Na₂CO₃ + 10H₂O → Na₂CO₃.10H₂O

Uses:

(i) Used in glass, soap and paper industries.

(ii) Used in the manufacture of borax.

(iii) Used as a cleansing agent for domestic Purpose.
