how will you show that exhaled air has more carbon dioxide than inhaled air
Answers
Answer:
Hello mate
Explanation:
Carbon dioxide turns lime water milky. Based on this principle, experiment can be designed to show that exhaled air has more carbon dioxide than inhaled air. Take two test tubes half filled with lime water.
ANSWER.
Limewater can be used to detect carbon dioxide. If carbon dioxide is bubbled through limewater then it turns from clear to cloudy/milky in colour. This is why limewater used in a simple respirometer can show that more carbon dioxide is present in exhaled air compared to inhaled air.
EXPLAIN:
exhaled air contain carbon doixide and when it comes contact with lime water, it turns milky. Turns lime water to milky because of the carbondioxide from the exhaled air. The carbon dioxide in our exhaled air reacts with the calcium hydroxide in the lime water to produce calcium carbonate which is milky in colour
