A standard hydrogen electrode (SHE) has several key characteristics. Here are some statements about it:

1. It is used as a reference electrode in electrochemical measurements.
2. Its potential is arbitrarily set at 0.00 volts.
3. It involves the half-reaction of 2H+ + 2e- → H2.
4. It requires a solution with a hydrogen ion activity of 1.
5. It operates at a temperature of 25 degrees Celsius (298 K).

If any statement contradicts these characteristics, it is not true for a standard hydrogen electrode. For example, a statement saying that the potential of a standard hydrogen electrode is not 0.00 volts would be false.
