How does clock in a clock reaction work
WebIn the presence of starch, the iodine intercalates into the helix structure and produces a dark blue color. Thus the "time" is set by the moles of the thiosulfate present. Once they are consumed, the clock turns blue. There are four reactions that are taking place within the clock reaction. Three bisulfite anions reacts with an iodate anion to ...
