5. Consider the following oxides of chromium: CrO2, CrO3, Cr2O3 c. Hence, place the three above-mentioned chromium oxides in order of increasing ph values (lowest to highest).
Accepted Answer
The oxides of chromium can be arranged in order of increasing pH as follows:
CrO3 This is because the acidity of the oxides increases as the oxidation state of the metal increases. CrO3 is an acidic oxide, while CrO2 is amphoteric and Cr2O3 is a basic oxide. Therefore, the pH values will increase as you move from CrO3 to Cr2O3.
