Q$3.$ Now consider the moment when the blue colour change is about to occur $($i$.$e$.$ when there is no more thiosulfate remaining in solution$).$

Based on the initial experiment and initial concentrations of reagents, calculate the concentrations of the reagents present in the flask at the moment just before the blue colour change begins $($ignore the starch, and the S$4$O$62-$ which is formed as the other by$-$product in this reaction$).$

Does Reaction $(1)$ continue beyond this point?

yes

no
