Answer 2

Explanation:

in our environment many things are colourless

For example Hydrogen gas is an colour less gas to find the liberation of hydrogen gas if we keep a burning match stick to it the burning match tick will burn with a poping sound

Another example of this is Carbon dioxide gas

in many chemical reactions carbon dioxide is liberated even in human body also carbon dioxide is liberated in the process of Respiration. To find this scientist have made many researchers. They found that if carbon dioxide gas reacts with lime water the lime water will turn into milky white.

Another way to determine the release of colour less gas Co2 is the matchstick test. If we being a match stick to Co2 it will put off .

so from the above discussion the liberation of colour less gas can be found by another chemical reaction
