Chromic acid (H 2 CrO 4) is a strong mineral acid that is toxic and corrosive and is a fire hazard (see the hazard information table). Its anhydrous form, chromium trioxide 1 (CrO 3), is also called ...

In this experiment, students determine the relative rates of oxidation by adding quantities of several different alcohols to a solution of chromium(VI) in dilute sulfuric acid and visually monitoring ...

AWE currently uses chromic acid anodising for passivating aluminium alloys to provide corrosion protection in a range of applications. Chromic acid anodising, however, gives rise to waste hexavalent ...

This study aims to leach chromium from coal fly ash using citric acid, oxalic acid and gluconic acid. Fly ash obtained from coal ash pond comprises of 28 ppm chromium. After the batch leaching ...
