Graham's law of diffusion experiment
WebAccording to Graham’s law, the ratio of the rates of diffusion is: rNH 3 /rHCl = (mwHCl/mwNH 3 ) 1/2 = (36.46/17.03) 1/2 = 1.463 Considering the crudity of the apparatus, the absence of a diffusion plug, the presence of convection currents, and the fact that solutions of different concentrations rather than gases are used, the results ...
