Assume 2 flasks each with one litre of a saturated solution of glucose(C6H12O6). One solution has one gram of glucose(C6H12O6) at the bottom. 100 g of glucose at the bottom was found by The other solution . The surface area of 100 g of glucose > than that of 1 g. give explanation why the solubility does not increase with the amount of solid deposited at the bottom of the flask?
