过硫酸铵是氧化剂还是还原剂

更新时间:2022-11-09 点击数:1738

很多人对过硫酸铵是氧化剂还是还原剂存在疑惑,实际上氢氧化钾厂家可以明确告诉您过硫酸铵是氧化剂。

Many people have doubts about whether ammonium persulfate is an oxidant or a reductant. In fact, potassium hydroxide manufacturers can tell you that ammonium persulfate is an oxidant.

过二硫酸根含有过氧基,是强氧化剂,可以把Mn2+氧化为MnO4-。

Persulfate contains peroxy group and is a strong oxidant, which can oxidize Mn2+to MnO4 -.

所以过硫酸铵溶液中除了大量的铵根离子和过二硫酸根离子外,还存在少量的硫酸氢根离子和硫酸根离子,溶液水解显酸性,加入硝酸可以抑制反应正向进行。

Therefore, in addition to a large amount of ammonium ions and persulfate ions, there are also a small amount of hydrogen sulfate ions and sulfate ions in the ammonium persulfate solution. The solution is acidic when hydrolyzed, and adding nitric acid can inhibit the reaction from going forward.
