Figure 9. Alkaline iodine-starch-solutions to which equal volume of glucose solutions with different concentrations were added. The pictures show different stages of the reaction (times as indicated). (1) c(glu) = 0,5 mol·L−1; (2) c(glu) = 0,2 mol·L−1; (3) c(glu) = 0,1 mol·L−1, (4) c(glu) = 0,05 mol·L−1
