D) turn the electrolyte into a paste

Question

Quizplus · Accepted Answer

The manganese dioxide and powdered carbon mixture in a 'dry Leclanche' cell act as a depolarising agent, which helps to maintain the cell's voltage and prevents it from being 'polarised', where the electrode potential decreases and the cell's output becomes weaker over time.
