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 WOULDREMOVE 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.
