Nitrogen dioxide sensor
Wireless nitrogen dioxide sensor: reactions of copper with nitric acid, nitrate decomposition, NO₂/N₂O₄ equilibrium, air quality studies.
Wireless digital sensor for measuring nitrogen dioxide concentration. Supports six educational experiments: monitoring the release of NO₂ during the interaction of copper with concentrated nitric acid, studying the decomposition of nitrates, demonstrating the reversible equilibrium of NO₂/N₂O₄ with temperature changes, monitoring the gas concentration in a closed vessel, assessing nitrogen oxides in a model polluted atmosphere and the absorption of nitrogen dioxide by an alkali solution.
- Observation of the release of nitrogen dioxide when copper reacts with concentrated nitric acid
- Study of the release of nitrogen oxides during the thermal decomposition of nitrates
- Demonstration of reversible equilibrium between NO₂ and N₂O₄ with temperature changes
- Monitoring the NO₂ concentration in a closed vessel during the reaction
- Assessment of the content of nitrogen oxides in a model polluted atmosphere (ecology)
- Study of nitrogen dioxide absorption by alkali solution
