Which gas is released when baking soda reacts with lemon juice or vinegar during cooking?
Carbon dioxide
Baking soda is sodium bicarbonate (NaHCO3), a mild base. Lemon juice contains citric acid and vinegar contains acetic acid (CH3COOH).
When they mix, a neutralisation reaction takes place, for example: NaHCO3 + CH3COOH → CH3COONa + H2O + CO2↑, and similarly with citric acid.
The fizz seen in the batter and the rising of cakes and dhoklas is due to the carbon dioxide gas released, which gets trapped in the dough and makes it porous and soft.
Hydrogen would need a metal + acid reaction, and oxygen or nitrogen are not products of an acid-carbonate reaction.
Hence, the answer is carbon dioxide.
