5. Given a solution with KCL 0.1M and Pb(NO3)2 (10^-5M) is bubbled with nitrogen and then with a dropping mercury electrode (drop time: 2 s; mass of mercury produced per 100 s: 0.15 g), the solution then scanned with a linear scan of the applied potential from 0.0 V to -0.9 V, measuring current at the same time. draw a sketch of the current/potential curve, label axis if possible. what reactions would occur at the electrode? where would the residual current and diffusion controleld limiting current be?
2.) Is the total concentration of current carriers (free electrons and holes) in a semicon- ductor equal to the concentration of valence electrons? 3.) There are two types of current carriers in semiconductors (free electrons and holes) and only one type in metals. Yet, metals are much better conductors of electric current. Is this because the currents of electrons and holes oppose each other?
