How do you make an ionic compound with chromium (III)?
Now, an ionic compound must be electrically neutral, which implies that the total positive charge coming from the cation must be balanced by the total negative charge coming from the anion. In this case, you need 2 chromium (III) cations and 3 oxide anions in order to have a neutral compound.
What happens when chromium (III) oxide reacts with acid?
Chromium (III) oxide is amphoteric. Although insoluble in water, it reacts with acid to produce salts of hydrated chromium ions such as [Cr (H . It is also attacked by concentrated alkali to yield salts of [Cr (OH)
