WebScience; Chemistry; Chemistry questions and answers; Write a balanced chemical equation (including states of matter) and a build a cell diagram for an electrochemical cell that has a copper cathode immersed in a solution of \( \mathrm{Cu}^{2+} \) ions, and a lead anode immersed in a solution of \( \mathrm{Pb}^{2+} \) ions.
WebReduction reactions occur at the cathode and oxidation reactions occur at the anode during electrolysis. For the half equation: Al3+ + 3e- → Al, this is described as a reduction reaction as... WebAnode. An anode is an electrode by which the conventional current enters into a polarized electrical device. In contrasts with a cathode, an electrode by which conventional current leaves an electrical device. A common mnemonic is anode current into the device. The direction of current in a circuit is opposite to the direction of electron flow.
