Could some one help me with the following question: Write the formulas of the compounds formed by Al3+ with the following anions: CN−, ClO3−, SO42−, H2PO4−.

You use the crossover rule for ions for each one.

Al(CN)3 Al has a charge of 3+, so you need 3 cyanides (charge of 1-) to balance out the charge.

Al(ClO)3

Al2(SO4)3

Al(H2PO4)3
