Because a water molecule is dipolar, the oxygen end of the water molecule forms the negatively charged end and the hydrogen end forms the positively charged end. If the metal electrode has excess negative charge, the water molecule gets oriented in such a way that its positive end is toward the metal electrode surface and its negative end is toward the excess positive charge in the solution. 4 (Bard & Faulkner, 2004). The line drawn through the center of these molecules is known as the inner Helmholtz plane.
