Question

how we get BAKING SODA from WASHING SODA..write chemical equation...!​

Answer 1

Answer:

Baking soda or sodium hydrogen carbonate produces sodium carbonate upon heating and further produces washing soda along with carbon dioxide and water, on recrystallization. The chemical formula for this is as follows: 2NaHCO3 heating  Na2CO3 + CO2 + H2O.

Answer 2

Answer:

Baking soda is sodium bicarbonate, NaCHO3. Simply heat the baking soda so that water (H2O) and carbon dioxide (CO2) are driven off, leaving you with sodium carbonate (washing soda). To save energy, it's a good idea to make this when you are already using the oven for other baked goods.
