  • Relative rates of diffusion. Vapors of HCI an NH3 arising from solutions on cotton swabs, diffused from opposite ends of the glass tube. A white fog of NH4CI appears where the vapors meet. Observe that fog formation started near the 18.5 cm mark on the ruler, about 10 cm from the HCI swab and 16 cm from the NH3 swab. the NH3 molecules therefore diffuse through air 16/10, or 1.6, times faster than the HCI molecules. The fact that 1.6 is very close to the square root of the molar ratio, shows that the relative rates of diffusion obey Graham's law approximately.
