NaHCO₃(s) + HNO₃(aq) → NaNO₃(aq) + H₂O(l) + CO₂(g)
Here's what happens in the reaction:
* Reactants:
* Sodium hydrogen carbonate (NaHCO₃): A white solid, also known as baking soda.
* Nitric acid (HNO₃): A strong acid.
* Products:
* Sodium nitrate (NaNO₃): A soluble ionic compound.
* Water (H₂O): A liquid.
* Carbon dioxide (CO₂): A gas, which is released as bubbles.
Explanation:
This is a classic acid-base reaction. The nitric acid (HNO₃) acts as an acid, donating a proton (H⁺) to the sodium hydrogen carbonate (NaHCO₃), which acts as a base. This results in the formation of sodium nitrate (NaNO₃), water (H₂O), and carbon dioxide (CO₂). The carbon dioxide gas is what causes the fizzing or bubbling you often see in this type of reaction.
