Electrolyte意思

"Electrolyte" is a term derived from the Greek words "electro-" meaning "electricity" and "lytēs" meaning "to loosen." In chemistry and physics, an electrolyte is a substance that, when dissolved in a solution (usually water), forms ions that can conduct electricity. This process is known as electrolysis.

Electrolytes are usually salts, acids, or bases that dissociate into cations (positively charged ions) and anions (negatively charged ions) when dissolved. The presence of these ions allows for the flow of electrical current through the solution. Common examples of electrolytes include sodium chloride (NaCl), potassium chloride (KCl), and sulfuric acid (H₂SO₄).

In the context of human physiology and sports nutrition, electrolytes refer to the minerals that are necessary for the proper functioning of the body, especially for maintaining the balance of fluids and regulating muscle function, including the heart. These electrolytes include sodium, potassium, chloride, magnesium, and calcium. They are lost through sweat and need to be replaced, especially during physical activity or in hot weather.

In the context of batteries and fuel cells, electrolytes play a crucial role in facilitating the movement of ions between the anode and the cathode, which is essential for the chemical reactions that produce electrical energy.
