3 function of salt bridges

• separate between two electrolytes

• maintain electrical neutrality

• complete the circuit by allowing electron to move between them

Info of oxidation

An Ox (oxidation no increase) X → X²+ + 2e^-

Info of reduction

Red Cat (reduction of oxidation number) X²^+ + 2e^- → X

How does the electron in Galvanic Cell moves?

from anode → cathode ( - → + )
