描述
产品介绍 Ammonium iron(III) sulfate dodecahydrate is often employed as an analytical standard, and has been used in a variety of other applications from nanomaterials to general redox reactions. This product is much less affected by oxygen in the air than iron(II) sulfate, making it more desirable for titration purposes, where iron(II) might be oxidized to iron(III). The oxidation of iron(II) to iron(III) is pH dependent, and the reaction occurs more rapidly at higher pH; this product lowers the pH of solutions slightly, thereby preventing oxidation from occurring.
