Light Scattering by Pure Water and Seawater: Recent Development

Figure 1

Diagram illustrating the random thermal motion of molecules inducing a change of density of a small volume element in pure water (a) and an electrolyte solution (b, c). Here, we assume the molecular mass for solutes (darker blue dots) is two times that of water molecules (lighter blue dots). Therefore, in (c), the exchange of two solute molecules with four water molecules does not change the density but alter the concentration of solute.
