Why starch is not soluble in water, Science

Assignment Help:

Starch  is not  soluble  in  water  ??

It forms colloid  in  aqueous medium  called  as micelles.  Iodine reacts with both amylose and amylopectin, but the former produces a complex that gives an intense blue colour and masks the violet colour of the complex formed by  the  latter. As a result, we observe a blue colour when  starch reacts with iodine. This colour complex dissociates  on heating and reforms again after cooling.
