Question

how does carbon dioxide gas arise from rhe solution of sodium carbonate and sodium hydrogen carbonate ? Explain with examples​

Answer 1

These weak acids react with sodium bicarbonate, releasing CO2 gas which causes cake batter and bread dough to rise and produces the tiny holes in cakes and breads. Sodium hydrogen carbonate dehydrates when it is heated, forming sodium carbonate. The CO2 can be recycled to produce more NaHCO3 by the Solvay process.

Answer 2

Explanation:

One of the raw materials for the process is limestone (calcium carbonate, CaCO3). Limestone is heated to produce carbon dioxide. The carbon dioxide is dissolved in water. ... When NaCl is added to aqueous NH4HCO3, a precipitate of sodium hydrogen carbonate, NaHCO3, forms.
