An electrolyte is “any compound that, in solution or in molten form, conducts electricity and is decomposed (electrolyzed) by it. It is an ionizable substance in solution”.
.An electrolyte is any substance that contains free ions that behaves as an electrically conductive medium (conducts electricity). All higher forms of life cannot exist without electrolytes, and that includes humans.
In our bodies, electrolytes include sodium (Na+), potassium (K+), calcium (Ca2+), bicarbonate (HCO3–, magnesium (Mg2+), chloride (C1–), hydrogen phosphate (HPO42-), and hydrogen carbonate (HCO3–). Electrolytes regulate our nerve and muscle function, our body’s hydration, blood pH, blood pressure, the rebuilding of damaged tissue. Various mechanisms exist in our body that keep the concentrations of different electrolytes under strict control.
