In most cases, only a certain maximum amount of solute can be dissolved in a given amount of solvent. If only a relatively small fraction of the dissolved substance undergoes the ion-producing process, the substance is a weak electrolyte (does not conduct electricity as well). You are accessing a machine-readable page. The Microtox, DTC is poorly soluble in aqueous media. Water is considered the universal solvent since it can dissolve both ionic and polar solutes, as well as some nonpolar solutes (in very limited amounts).
