Applications of Surface Charge
Charged surfaces are extremely important and are used in many applications. For example, solutions of large colloidal particles depend almost entirely on repulsion due to surface charge in order to stay dispersed. If these repulsive forces were to be disrupted, perhaps by the addition of a salt or a polymer, the colloidal particles would no longer be able to sustain suspension and would subsequently flocculate.

“The Germans are called brutal, the Spanish cruel, the Americans superficial, and so on; but we are perfide Albion, the island of hypocrites, the people who have built up an Empire with a Bible in one hand, a pistol in the other, and financial concessions in both pockets. Is the charge true? I think it is.”
—E.M. (Edward Morgan)
