ok it depends upon when you do starch test the leaf without soda lime will have more starch in it as compare to leaf with soda lime

So when you put iodine solution on leaf without soda lime on first day then it will turn blue black

But when you put iodine solution on leaf with soda lime then it will show no change since there is no starch in it on first day itself

Also if you will test starch after 3 or 4 days both the leaves will have no starch


sanjana188: if there is no starch on soda lime leaf i think it will turn brown indicating that there is no starch
mealwayshappy2003: Yup that's correct... I was bit confused whether it turns blue black or decolorise
sanjana188: oh
