Question

What is the chemical name and chemical formula of washing soda. how is it obtained from sodium chloride? Give equation of the reactions

Answer 1

HERE IS THE ANSWER.
_______________________
Chemical Name - sodium carbonate.
chemical formula - Na²CO³.

the reaction for obtaining it from sodium chloride is:
2NH³ + CO² +H²O --->2NH⁴HCO³.
now this ammonium bicarbonate reacts with NaCl to give sodium bicarbonate which is further heated to produce sodium carbonate.
NH⁴HCO³+NaCl --> Na²HCO³ + NH⁴Cl.
NaHCO³ ---∆--> Na²CO³ + CO² + H²O.

Answer 2

Here is your answer

2NH³ + CO² +H²O --->2NH⁴HCO³.
this ammoniumbicarbonate reacts with NaCl to give sodiumbicarbonate which is further heated to produce sodiumcarbonate.

The reaction for obtaining it from sodium chloride.

hope it helps you
