The diagram shows the apparatus set-up for an experiment. Gas jar ( A) contains a brown gas, nitrogren dioxide and gas jar ( B) contains hydrogen > The molecular masses of nitrogen dioxide and hydrogen are 46 and 2 respectively.

Describe and explain the follwoing observations in the two gas jars as the experiment proceeds.
The colour of the gas.

Text Solution

Verified by Experts

The colour of the gas `:` The colour of the gas in both jars becomes the same ( light brown ) after a few minutes. Diffusion has taken place. Nitrogen dioxide particles will diffuse into the spaces between the hydrogen particles. At the same time, hydrogen particles will diffuse into the spaces between nitrogen dioxide particles. Eventually, each gas jar will contain a mixture of nitrogen dioxide and hydrogen gas.
