In undergraduate chemistry teaching labs, an Fe solution, normally of unknown
concentration, is titrated with a KMNO, solution of exact concentration (assume 0.062
M). The 'endpoint is detected when the purple color of permanganate persists. Give
the (balanced) reactions that are occurring and explain the titration experiment at
various stages, using the Nernst equation.
