Eperimental Measurements of the Hall Effect in Very Dilute Solutions

Abstract
A brief historical account of the Hall effect in very dilute solutions is given in which the interest in Hall effect measurements for the knowledge of electrolytes is shown. Then a systematic examination is presented of the different parasitic voltages which are likely to appear in a Hall cell. The criteria to which the experimental setup must conform to allow detection of the Hall voltage are defined. (This voltage is from 0.1 to 1 µV in our experiments.) Results of measurements in hydrochloric and nitric acid solutions are given confirming the theoretical predictions.
