Common mistake
Hydrogen Production Prediction Error
Students often incorrectly predict that hydrogen is produced at the cathode regardless of the metal's reactivity.
Remind students to compare the reactivity of the metal with hydrogen; hydrogen is produced only if the metal is more reactive than hydrogen.
