Dispersions: What is the difference between a dispersion and a suspension?
Answer: A dispersion is a mechanism where any matter at all is spreading to a point of reaching an equilibrium in all directions, i.e. heating up a room to the point of the same temperature throughout. Pico and nano metre sized atomic silver clusters subject to a hydrophilic relationship with the water in which they are suspended, carry a minus and mutually repelling electrical interfacial charge known as the Zeta potential.
