- 1電解質(運動飲料上寫的也是這個詞;科學上原指能導電的液體)
In the science sense, an electrolyte is a liquid (or a melted substance) that lets electricity pass through it. The current can travel because the liquid has charged particles that can move. Salt water is a simple example; pure water is a poor one. Though actually, everyday English has stretched the word. On sports bottles and in clinics, “electrolytes” often means the body salts themselves — sodium, potassium, and the rest — that you lose in sweat, not the liquid as a whole. Scientists still use the older, stricter sense Faraday named. It is a school-science and medical word; drinks ads use it more loosely than a chemistry teacher would.
組成electro- (electricity) + -lyte, taken from electrolysis. The British scientist Michael Faraday coined the word in 1834.
