WitrynaImagine that instead of a negatively charged plate, our plate is positively charged. Our positive particle would be pushed away from the plate since they are both positively charged. This time, we have to put in energy to try to move the particle closer to the plate, instead of to pull it away. WitrynaIn the case of trivalent ions such as La 3+, bulk concentrations in excess of 10 −5 M can neutralize a negatively charged surface and even lead to charge reversal wherein the cations continue to adsorb onto a surface that is already net positively charged (see Problem 3. 2 (ii)).
