Answer:
Electrolyte
Step-by-step explanation:
Wet cells are rechargeable cells that contain electrolytes such as sulphuric acids.
An electrolyte is a solution that contains ions or charged molecules/atoms.
Due to their ability to undergo ionic dissociation, they can allow the conduction of electric charges
Therefore, the wet cell uses weak acid or salt solution as the electrolytes through which electrons can migrate from positive to negative electrode and vice-versa
