write the lab activity which explaus rate of diffusion of gases
Answers
Answer:
In this experiment, the relative rates of diffusion of two gases will be determined. ... Therefore, if ammonia gas and hydrogen chloride gas are released simultaneously at opposite ends of a glass tube, a white ring of smoke will form at the location where they meet.
Explanation:
Example of diffusion: Gas Exchange
The process of moving oxygen into the cells, and carbon dioxide out, occurs because of the concentration gradient of these substances, each moving away from their respective areas of higher concentration toward areas of lower concentration.
Answer:
Experiment # 1
Diffusion of Solid in Liquid:
Experiment:
A beaker is almost filled with water. Some crystals of CuSO4 or KMnO4 are dropped carefully without disturbing water and is left as such for some time.
Observation:
The water is uniformly coloured, blue in case of CuSO4 and pink in case of KMnO4.
Inference:
The molecules of the chemicals diffuse gradually from higher concentration to lower concentration and are uniformly distributed after some time. Here, CuSO4 or KMnO4 diffuses independently of water and at the same time water diffuses independently of the chemicals.
