Question
Which one of the following compounds is formed when sodium hydrogen carbonate reacts with hydrochloric acid?
- NaCl
- Water
- CO2
- All of the above
Hint:
During a chemical reaction, carbon dioxide gas is released as effervescence or bubbles. Metal carbonate and bicarbonate gets decomposed rarely with help of mineral acids with the evolution of CO2. 
The correct answer is: All of the above
CO2, H2O, and NaCl- All of the above are formed when sodium hydrogen carbonate reacts with hydrochloric acid.
- Sodium hydrogen carbonate (NaHCO3)on reaction with hydrochloric acid (HCl) gives sodium chloride(NaCl), water(H2O) and releases carbon dioxide (CO2 gas) effervescence or bubbles.
