Consider an electrochemical cell consisting of a zinc electrode in one half-cell and a copper electrode in the other half-cell. The zinc electrode has a surface area of 5 cm² and is placed in a 0.1 M ZnSO₄ solution, while the copper electrode has a surface area of 10 cm² and is placed in a 1.0 M CuSO₄ solution. Calculate the polarization of the cell when a current of 0.5 A is passed through it.

A student wishes to determine the standard reduction potential of an unknown metal electrode in a half-cell. They set up an electrochemical cell using a known standard hydrogen electrode (SHE) as the reference electrode and the unknown metal electrode as the working electrode. A voltmeter is used to measure the potential difference between the two electrodes. The reading is +0.45 V. What is the standard reduction potential of the unknown metal electrode in volts?
