Question
What happens when a solution of sodium hydrogencarbonate is heated? Write equation of the reaction involved.
Solution
When a solution of sodium hydrogen carbonate (NaHCO3) is heated, it decomposes to give sodium carbonate (Na2CO3) with the evolution of carbon dioxide gas.
2NaHCO3 → HeatNa2CO3+ CO2 +H2O +">NaHCOHeat→Na2CO3+CO2+H2O

Dry HCl gas does not change the colour of dry blue litmus paper. Why?
Read the following statements:
I. When a red litmus paper is dipped into reaction mixture of a saponification reaction, it turns blue and the reaction is exothermic.
II. When a blue litmus paper is dipped into reaction mixture of a saponification reaction, its colour does not change and the reaction is exothermic.
III. When a red litmus paper is dipped into reaction mixture of a saponification reaction, its colour does not change and the reaction is endothermic.
IV. When a blue litmus paper is dipped into reaction mixture of a saponification reaction, its colour does not change and the reaction is endothermic.
