concentration cells

A concentration cell is a type of electrochemical cell where electricity is generated from the difference in the concentration of ions between two solutions. It consists of two electrodes connected by a circuit, with each electrode immersed in solutions of the same material but at different concentrations. The difference in ion concentration causes a flow of electrons from the side with lower concentration to the side with higher concentration, creating an electrical voltage. This process continues until the concentrations balance out, effectively converting chemical energy into electrical energy through natural diffusion.
