Calculate the half cell potential for the reduction of Pb(II) to metallic Pb(I) in a saturated Lead(II) sulfate solution (with a concentration of [1.5 x 10^-5 mol/L]
A solution was made by taking 1.250g of KMnO4 and dissolving it in enough water to make 1.000 liter of solution. This solution was used to titrate H2C2O4·2H2O, a very pure substance. In acidic media, the reaction is.
