AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The chemical name of baking soda is Sodium hydrogen carbonate (also called sodium bicarbonate). Its chemical formula is NaHCO₃.
Examiners expect both the chemical name and formula for full marks. "Sodium bicarbonate" is also accepted, but "sodium hydrogen carbonate" is the preferred IUPAC/NCERT name. Writing only the name or only the formula would likely lose half the credit.
