Problem- A method for determining the quantity of dissolved oxygen in nautral water reequires a seris of redox reactions. Balance the following chemical equations in that series under the conditions indicated: (If you could show a majority of the steps or the "most important" ones it would be appreciated)
1) Mn+2 (aq) + O2 (g) ---> MnO2 (s) ....Basic solution
2) MnO2 (s) + I- (aq) ---> Mn+2 (aq) + I2 (s)....Acidic solution
3) I2 (s) + S2O2-3 (aq) ----> I- (aq) + S4O2-6 (aq) ...neutral solution
I want you to clarify the chemistry in this above problem.
