Spectatorions旁观离⼦
今天看到了⼀个很有意思的词spectator ions旁观离⼦，以前学化学的时候没有注意到。就像上图中的反应⽅程式，硝酸根和钠离⼦反应前后都没有发⽣变化，这个就是旁观离⼦。
A spectator ion is a charged atom or group of atoms in a chemical reaction that does not undergo a chemical change or change state when the reaction takes place. In chemical reactions, compounds that contain ions are often dissolved in water, resulting in a state called aqueous ions. When two ionic compounds are dissolved into an aqueous state, or both are dissolved into the same solvent, their ions parate, so any ions that made up the first compound can interact with any ions from the cond compound. It is not necessary for all ions to interact in this state, and if some ions do not interact, they usually
remain dissolved in solution.
