Qualitative analysis: Verify inferences for effervescence with dilute HNO3 and CO2.

Let's check your observations and inferences for the qualitative analysis experiment. Part (a) and (c): Initial tests on C Test: C + dil HNO₃ + stir Observation: Effervescence occurs, which is a colourless, odourless gas. The gas turns moist blue litmus paper red and also turns limewater milky. Inference: Acidic gas, CO₂ gas from CO₃²⁻ present. Verification: The observation of effervescence with acid, producing a colourless, odourless gas that turns limewater milky, is characteristic of carbon dioxide ($

Test: $\text{C} + \text{dil HNO}_3 + \text{stir}$ $C + dil HNO_{3} + stir$
- Observation: Effervescence occurs, which is a colourless, odourless gas. The gas turns moist blue litmus paper red and also turns limewater milky.
- Inference: Acidic gas, $\text{CO}_2$ gas from $\text{CO}_3^{2-}$ present.
