MHT CET 2026 Chemistry question
A galvanic cell consist copper electrode and standard hydrogen electrode. If , then identify a reaction taking place at positive electrode during working of cell.
Answer: (B)
Solution
The SHE has by convention, while is higher, so copper has the greater tendency to be reduced. Hence the copper electrode is the cathode (positive electrode in a galvanic cell) and the SHE is the anode (negative electrode). The cell reaction
