Answer:
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.
