Electrical conductance is a physical property that depends on the presence of ions capable of carrying an electrical charge. Strong and weak electrolytes are associated with the degree of ionic dissociation of a substance in a medium; strong electrolytes dissociate completely, while weak electrolytes dissociate only partially [A1.1]. This difference in ion release explains their distinct electrical conductivity and their role in hydration. In this context, the objective of this research was to experimentally analyze the relationship between the electrical conductance present in energy drinks, sports drinks, and oral rehydration solutions. An experimental procedure was developed in which six samples (two energy drinks, two sports drinks, and two oral rehydration solutions) were evaluated. These samples were coded as BE, BD, and SRO, respectively, followed by the corresponding number to ensure sample confidentiality. A conductivity meter was used as a measurement tool to verify the electrical conductance of the samples, allowing for the classification of the solutions. An analysis of product labels was performed to identify the presence of ions and classify the samples as strong, weak, or non-electrolytes. Among the results, oral rehydration solutions showed higher electrical conductance, consistent with their high sodium and potassium concentrations. In contrast, some sports and energy drinks did not demonstrate such high conductance, [A2.1] associated with a lower electrolyte content.
