and

Thus the value obtained for the specific ionic velocity is independent of the E.M.F. applied, i.e., the velocity of the ions is proportional to the potential gradient.

New solutions were afterwards set up and the experiments with the large E.M.F. repeated. The results were—

Movement upwards:

Means:

Movement downwards:

Means:

Mean of $$v_1$$ in both directions = 0.00046.

Taking the mean value deduced from all three series of separate experiments, we get
