The volume of K2C12O7 (aq) used was justsufficient to oxidize all the Sn²a) in 10.0 mL of the solution Calculate the concentrationof the Sn2*ag) ions in the solution. What colour change indicated the end point of thiscalculation? Explain.1.2. What volume of 0.0500 mol/L KMNO4 (gg) is needed to oxidize all the Br (ag) ions in 25.0mL of an acidic 0.200 mol/L NaBr (ag) solution? What colour change indicates the endpoint of the reaction?
