These steps take place in an activity to prove that chlorophyll is essential for photosynthesis. The aforementioned step is carried out to prove the presence of chlorophyll. Chlorophyll is not soluble in water but can dissolve in alcohol as alcohol is an organic solvent. Hence the leaf is put in alcohol to remove the chlorophyll. The alcohol turns slight green. Heat is given to increase the solubility of chlorophyll in alcohol. As alcohol is an inflammable substance, it is boiled over a water bath
