WebThe overall reaction is thus: I− 3 + 2 S2O2− 3 → S4O2− 6 + 3 I− ( Ereaction = +0.46 V) For simplicity, the equations will usually be written in terms of aqueous molecular iodine … WebThe weak iodo-starch reaction shown by the supernatant of the reaction mixture suggested that a 42.2％ （w/w）sucrose solution inhibited the collapse of the rice starch. We experimentally produced rice-an paste from 20 g of rice flour by heating it with 25 g of sucrose and 55 g of distilled water at 80℃ for 1.5 hours.
