cation - ( x, y ,z)

Anion - ( A,L, D,F )

consider : P+m - cation

Q^n- : Anion

(1) x + A : xa^2

x^2, A- —> xa2

x + L : XL , x^2 + L^2- —> XL

x + D : (1) x + f = XF : x^2 + F^2-

(2) Y + A = (2) Y + L : Y2L : ( Y+, L^-2 —> Y2L )

Y + D : Y3D : Y+, D3- : Y3d

Y+ F : Y^+ + F^-2 = Y2F (3)

(4)

Z + A : z^3+ + A- —>  ZA3 (Z+L= 4)

Z + D : ZD : Z ^+3, D^3- —> ZD

Z + F : Z2f3 : Z^3+  + F^2- —-> Z3F2

*

X^2, y^+1, Z^+3 - cation

A^-1, L^-2, D^-3, F^-2 : Anion

part B

1 : x^2 + D^3- = X3D2

2 : Y+ A : Y^+  +  A - = YA

3 : Y + F : Y^+ + F^2- = YF2

4 : Z+ L = z^3 + L^2- = Z2L3
