Abstract

In this work, the solubilization and diffusion of magnesium chloride in aqueous media was studied. For this end, electrical conductivity tests with different probe and MgCl₂tablet positions. Regardless of the probe and tablet geometric configurations, all tests followed the same methodology: an MgCl₂ tablet, previously pressed, was placed in a container in a given location with deionized water, and the electrolyte conductivity was measured versus time. The tests were performed without stirring, i.e., under static conditions to avoid interference from other phenomena, such as convection. However, even without stirring, the convection occurred due to gas liberation from formed tablet porous or by liberation of particles due to the gravity.
