The term 'polarisation' describes
A) the polarity of a cell's electrodes
B) the reverseal of a cell's polarity
C) the formation of hydrogen gas bubbles on the positive electrode

Question

Quizplus · Accepted Answer

Polarisation in the context of electrochemistry often refers to the process where gas bubbles, such as hydrogen, form on the electrodes of a cell, particularly on the cathode during electrolysis. This can interfere with the cell's operation by increasing its internal resistance and decreasing its efficiency.
