electrolyte JUST WRITTEN FOR YOU

/ɨˈlɛk.tɹɵˌlaɪt/ · e·lec·tro·lyte
noun
  1. A substance that, in solution or when molten, ionizes and conducts electricity. Saline water acts as an electrolyte, allowing current to flow through it.
  2. Any of the various ions (such as sodium or chloride) that regulate the electric charge on cells and the flow of water across their membranes. During intense exercise, athletes lose electrolytes like potassium and need to replenish them.
Did you know? The term gained popular attention in the 20th century thanks to sports drinks, which are formulated to replace the electrolytes lost through sweat during vigorous activity.
