The correct answer is option 2. Both Assertion and Reason are correct, and Reason is not the correct explanation of Assertion. Sodium carbonate can indeed be obtained by heating baking soda (sodium bicarbonate). The chemical reaction is: \[ 2 \text{NaHCO}_3 \rightarrow \text{Na}_2\text{CO}_3 + \text{H}_2\text{O} + \text{CO}_2 \] |
