2 questions on electrochemical reactions. Each opens in the question browser with its memo.
Electrolysis of concentrated copper II chloride solution using carbon electrodes. Define electrolysis, write anode reactions showing halide ion oxidation, identify the major product formed at the cathode, and determine products formed when zinc iodide is added to the electrolyte.
Standard galvanic cell with cadmium and chlorine gas electrodes. Define galvanic cell, write cell notation, determine electron flow direction, write the reduction half-reaction, and explain how chloride ion concentration affects cell potential (emf).
