The electrolyte in vented nickel-cadmium batteries is a strong solution of which chemical?

Explanation:
In vented nickel-cadmium batteries, the electrolyte is a strong alkaline solution that provides the hydroxide ions (OH–) needed for the nickel and cadmium electrode reactions. The typical choice is potassium hydroxide, which offers high ionic conductivity and chemical stability with the NiOOH/Ni(OH)2 and Cd/Cd(OH)2 electrodes. This alkaline environment supports the surrounding chemistry and minimizes corrosive effects that acids would have, making potassium hydroxide the electrolyte of choice.
