Imagine that a and b are cations and x, y, and z are anions, and that the following reactions occur: ax(aq)+by(aq)→no precipitate, ax(aq)+bz(aq)→precipitate. which of the following choices is insoluble? a. ax ay b. az bx c. by bz

b. AZ BX

Explanation:

A⁺, B⁺, X⁻, Y⁻ and Z⁻

AX(aq)+BY(aq)→no precipitate

AX(aq)+BZ(aq)→precipitate.

AX(aq)+BY(aq)→no precipitate:

A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Y⁻ (aq) → AY (aq) + BX (aq)

AX(aq)+BZ(aq)→precipitate:

A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Z⁻ (aq) → AZ (s) + BX (aq)

Considering the reactions above, the insoluble specie is AZ.
