because it is a weak and unstable
Fajans rules show that the simple trivalent cation Al3+ is not expected to be found in anhydrous salts or binary compounds such as Al2O3. The hydroxide is a weak base and aluminium salts of weak acids, such as carbonate, can't be prepared. The salts of strong acids, such as nitrate, are stable and soluble in water, forming hydrates with at least six molecules of water of crystallization.

Carbonates are salts of carbonic acid which itself is very unstable and ceases to exist under normal atmospheric pressure.

because they are not friends since aluminium perved over carbonates mum in the bathroom

al has a valency of 3+
co3 has a valency of 2-
If these two were gtting together you would need 3 co3 and 2 Al
too unpredicatble and the molecule would just split apart

I am glad you are gettig clever answers to your question. Can any chemistry minded person answer mine ? I wondered how toxic fluoride is.
