Resumen
Gives a conductive method for determining the rate of solution. Describes the principles of the procedure by dissolution of an agreed test portion in water at an agreed temperature, with controlled agitation. Measurement of the conductivity of the solution, at certain intervals, of the final conductivity (when the sample is completely dissolved) and calculation of the ratio of conductivities to the final conductivity at an agreed time, thus, a measure of the rate of solution is obtained. Details of the laboratory stirrer are illustrated in a figure.
