A solution contains 15mL 0.1 M KI, 15 mL of DI water and 5 mL o f3% H2O2. After the decomposition of H2O2 is complete, you titrate the solution with 0.1 M AgNO3. If the catalyst, I-, is not consumed in the reaction and is completely recovered, what volume of the 0.1 M AgNo3 if required to reach the end point?
A 1.0-L buffer solution is 0.105M in HNO 2 and 0.145M in NaNO 2. Determine the concentrations of HNO 2 and NaNO 2 after addition of 1.4g NaOH.
