Question
To detect the bicarbonate present in any given sample, sample is heated. Which of the following gas is released during this reaction is used to detect bicarbonates?
- Carbon dioxide
- Water vapor
- Carbon monoxide
- Methane
Hint:
The air/gas we respire out.
The correct answer is: Carbon dioxide
The correct option is a)Carbon dioxide.
At temperatures above 176 degrees Fahrenheit (80 degrees Celsius), sodium bicarbonate begins to decompose into three compounds, forming sodium carbonate (Na2CO3), water (H2O), and carbon dioxide (CO2).

In the laboratory preparation of carbon monoxide, hydrochloric acid is only used although sulfuric acid reacts with calcium carbonate in the same way as HCl. However, the sulfuric acid is never used because:
(i). Insoluble calcium sulfate formed during this reaction
(ii). Calcium sulfate covers the marble chips and stops the reaction.
(iii). The reaction is a highly exothermic reaction
(iv). To react both of the reactants, many temperature conditions need to be fulfilled
