What is the Standard Hydrogen Electrode?
Practice Version
Standard Hydrogen Electrode:
The standard electrode against which the reduction potential of all electrodes can be measured. Standard hydrogen electrode. The standard hydrogen electrode is a reference electrode used to measure the voltage of other electrodes in an electrochemical cell.
Example:
Imagine you're at a party trying different foods, and you need a standard dish to cleanse your palate and compare the flavors of everything else. Similarly, in electrochemistry, the standard hydrogen electrode (SHE) acts as a reference point against which the reduction potential of all other electrodes can be measured. Just as that standard dish helps you gauge and contrast the taste of various foods, the standard hydrogen electrode provides a baseline, allowing scientists to determine and compare the electrochemical properties of different reactions.
