Questions & Answers
QUESTION:
Which oxide \(Cr{O_3}\) or \(CrO\) is more acidic in water? Why?
ANSWER:Step 1 of 3
The given compounds are \(CrO_3\) and CrO.
Between \(CrO_3\) (chromium trioxide) and CrO (chromium (II) oxide), \(CrO_3\) is more acidic in water. It is because \(CrO_3\) can act as a strong oxidizing agent, generating more protons (\(H^ + \)) when it reacts with water.

Compare the acidity of chromium trioxide (CrO?) and chromium (II) oxide (CrO) in water. Chromium trioxide forms strong chromic acid increasing hydronium ions, while chromium (II) oxide has weaker oxidizing properties, resulting in a less acidic solution.
