WebNov 13, 2024 · Figure 17.5. 2: Brownian motion of a particle in solution. When thermal motions occasionally release a solute molecule from this trap, it will jump to a new location. The jumps are very fast (10 –12 - 10 –13 sec) and short (usually a few solvent-molecule diameters), and follow an entirely random pattern, very much as in Brownian motion.
