Why green leaf is boiled in alchohol before testing it in starche?

Answer»

Hi mate☺☺☺❄❄❄⛄⛄⛄⛄



We boil the leaf in alcohol when we are testing it for starch as this WOULD REMOVE the CHLOROPHYLL from the GREEN leaf. 

Decolorised leaf is then treated with iodine and a BLUE black colour is obtained which confirms the presence of starch in the green portion of the leaf.
