How to make an air pollution detector with the following materials indicator paper, chemical d yes,metal films , lichens, reactive gels, and solid sorbents.

Answer 1

To make an air pollution detector with the materials listed, follow these steps:

1. Prepare the indicator paper by coating it with the chemical dye. This dye will change color in the presence of certain pollutants.

2. Attach metal films to the indicator paper. These films will act as electrodes and help in detecting pollutants.

3. Place lichens on the indicator paper. Lichens are sensitive to air pollution and can be used as bioindicators.

4. Mix reactive gels and solid sorbents and place them on the indicator paper. These materials will help in adsorbing and detecting pollutants in the air.

5. Connect the metal films to a circuit or sensor that can detect changes in the indicator paper caused by air pollution.

6. Place the air pollution detector in an area where you suspect pollution levels may be high.

7. Monitor the detector regularly and note any changes in the color of the indicator paper or readings from the sensor.

By following these steps and using the materials listed, you can create a simple and effective air pollution detector for monitoring air quality in your surroundings.
