Final answer:

The statement that chromium reacts with water to make chromium oxide is not accurate; chromium is resistant to corrosion and does not easily react with water to form such compounds.

Step-by-step explanation:

The statement that chromium reacting with water to make chromium oxide is somewhat misleading. While chromium compounds are used in various industries and environmental settings, the reactivity of metallic chromium with water under normal conditions is very low. This is in part because one of the chemical properties of chromium is that it is resistant to corrosion and does not readily react to form compounds like chromium oxide with water.

Chromium predominantly exists in the forms of Cr(III) and Cr(VI) in the environment, where Cr(III) compounds are poorly soluble in water and Cr(VI) compounds have reasonable solubility. Furthermore, when it comes to amphoteric oxides like chromium(III) hydroxide, Cr(OH)3 or Cr2O3•3H2O can react with both acids and bases, making it more complex than a simple reaction with water.
