Question

How will you justify that heating of washing soda into soda ash is

decomposition type of reaction? Write equation.​

Answer 1

Explanation:

HERE IS YOUR ANSWER ~

chemical formula of washing soda is =

NA² CO³ . 10H²O

Washing soda can be obtained by heating backing soda .

On heating backing soda gives sodium carbonate , carbon dioxide and water .

Answer 2

Heating of washing soda into soda ash is  decomposition type of reaction which can be justified as follows:

• In decomposition reactions, the reactant breaks down into simpler compounds.
• For instance, when washing soda (i.e. sodium carbonate decahydrate) is heated very strongly, it loses water of crystallization to give rise to soda ash ( i.e. anhydrous sodium carbonate)
• The underlying reaction is as follows:-

        Na₂CO₃.10H₂O →   Na₂CO₃.H₂O → Na₂CO₃
