Al(C 2 H 3 O 2 ) 3 - first, aluminium is in the beginning of the equation and acetate needs to be after. Aluminium has a charge of +3 making it Al +3 -acetate has a charge of -1 and its formula is C 2 H 3 O 2 - Using the crossover method, we see that it would take three acetate ions (-1 charge) to balance out the 1 Aluminium Ion (+3 charge). So the final equation should be Al(C 2 H 3 O 2 ) 3
