Formula of the compound : X3Y
b) X^2+ cation and HY^- anion
Formula of the compound : X(HY)2
c) X^3+ cation and HY^2- anion
Formula of the compound : X2(HY)3
The Crisscross method is a method of finding out the chemical formula of a metal and non-metal that combine to form an ionic bond.
To use this method, the absolute value of the oxidation number of the first ion is used as the subscript of the second, and vice versa. The subscripts are then reduced by the greatest common factor.
