Question

Show that absorption is directly proportional to concentration

Answer 1

Answer:

in the experimental setup of determining the presence of carbon dioxide in respiration make two congruent setups with two potassium hydroxide solutions of different concentrations

after the end of the reaction you will find the setup having more concentrated potassium hydroxide is able to raise more water in the tube where as the potassium hydroxide in the setup of lower concentration is able to raise comparatively low water in the tube

hence concentration of a solution is directly proportional to absorption
