At nearly 70^ C , sodium bicarbonate shows the property of gradually decomposing, which makes it usable in bakery products. The product of decomposition responsible for this use of sodium bicarbonate is
Options
- ACarbon dioxide
- BHydrogen
- CWater vapour
- DOxygen
Correct answer
A. Carbon dioxide
Step-by-step solution
Above 70^ C , sodium bicarbonate gradually decomposes into sodium carbonate, water and carbon dioxide as follows -2 NaHCO ₃- Na ₂ CO ₃+ H ₂ O + CO ₂ , In bakery, it reacts with other components or decomposes at higher temperature to release carbon dioxide, which causes dough to rise.
