I can provide a general definition of electrolytes, but the search results do not contain specific information about the role electrolytes play in a horse’s hydration.
In chemistry and physics, an electrolyte is a substance that conducts electric current. This conduction results from the dissociation of the substance into positively and negatively charged particles called ions. These ions migrate toward and are discharged at the cathode and anode of an electric circuit.
Acids, bases, and salts are the most familiar electrolytes, and they ionize when dissolved in solvents such as water or alcohol. Many salts, like sodium chloride, act as electrolytes when melted without a solvent. Some electrolytes, such as silver iodide, remain electrolytes even when solid.
