What is the term for the group of minerals that take on a charge when dissolved in water?

The term that accurately describes the group of minerals which take on a charge when dissolved in water is "Electrolytes." Electrolytes are essential for various physiological processes within the body, including the regulation of fluid balance, muscle contractions, and nerve signaling. When dissolved in water, these minerals dissociate into their ionic forms, becoming positively or negatively charged, which is critical for maintaining electrical neutrality and enabling the conduction of electrical impulses.

In contrast, trace minerals, macrominerals, and ultratrace minerals refer to classifications of minerals based on how much is required by the body rather than their behavior in solution. Trace minerals are needed in smaller amounts, macrominerals in larger amounts, and ultratrace minerals in very minute amounts, yet none of these categories specifically denote the property of forming charged ions in solution as electrolytes do.
