What is a concentration cell and how does it work?

A concentration cell is a limited form of a galvanic cell that has two equivalent half-cells of the same composition differing only in concentrations.

A concentration cell acts to dilute the more concentrated solution and concentrate the more dilute solution, creating a voltage as the cell reaches an equilibrium.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

catya that's not even a b or c
