### Step-by-Step Solution: 1. **Definition of Standard Hydrogen Electrode (SHE)**: - The Standard Hydrogen Electrode (SHE) is a reference electrode used in electrochemistry to measure the electrode potential of other electrodes. It consists of a platinum electrode in contact with hydrogen gas at a pressure of 1 atm and a solution of hydrogen ions (H⁺) at a concentration of 1 M. 2. **Inert Nature of Platinum**: - Platinum (Pt) is classified as an inert metal. This means it does not easily react with other substances and does not corrode. This property is crucial for the stability of the SHE, as it ensures that the electrode remains unchanged during the electrochemical reactions. ...
