Yes, aluminum chloride (AlCl3) exists. It is a compound formed by the combination of one aluminum atom with three chlorine atoms.
Aluminum chloride, with the chemical formula Al2Cl6, is a white or colorless solid compound that is highly soluble in water. It is commonly used in industrial processes such as in the production of organic compounds and as a catalyst for Friedel-Crafts reactions.
No compound exists with this formula. However, CaCl2 (with a lowercase L) is calcium chloride, which is an ionic compound.
No such compound exists. Perhaps what is mean is Al2(CO3)3 which is aluminum carbonate.
I don't think this compound actually exists.
