AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Baking soda has the chemical name sodium hydrogen carbonate (or sodium bicarbonate) and its chemical formula is NaHCO₃.
This is a standard 1-mark factual recall question. Examiners expect both the chemical name and formula. "Sodium bicarbonate" is also accepted, but "sodium hydrogen carbonate" is the IUPAC-preferred name used in the NCERT textbook. Writing just one without the other may cost you the mark.
