Question

A mixture of hydrogen and chlorine can be separated by passage through a porous pot.
A.True
B.False

Answer 1

We have to remember that a porous pot works on the principle, that when there are two substances in the pot the densities of the two substances will be different. The less dense gas will escape first and the denser will remain back. The gas thus escapes the pot because the environment inside and outside is different and to match the gap. The gas leaves out.

Complete step by step solution:
As per the question, let’s consider in a porous pot we have a mixture of hydrogen and chlorine.
We know that the density of hydrogen is $0.9gm/litre$ and density of chlorine is $35.5gm/litre$.
Here it is clearly visible that the density of chlorine is very high than the density of hydrogen.
As a result, hydrogen gas will diffuse more than chlorine in a porous pot.
Hence, the chlorine will remain outside the pot.
Hence, proved. The above statement is true that:
A mixture of hydrogen and chlorine can be separated by passage through a porous pot.

Note: We have to remember that a porous pot was initially invented for Daniel Cells. In which it played two major roles-
One to complete the circuit by allowing the ions to pass through and second to provide a separation between two solutions and prevent it from mixing. It was invented so as to separate hydrogen gas from the porous pot. We cannot physically separate the two gases as they are both in the same state of matter even in a porous. Through the process of diffusion both can be easily separated due to the big difference in densities.
