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?

AX
AY
AZ
BX
BY
BZ

Respuesta :

AZ is the precipitate

Explanation:

We have the first chemical reaction:

AX (aq) + BY (aq) → AY (aq) + BX (aq)  (no precipitate)

And the second chemical reaction:

AX (aq) + BZ (aq) → AZ (s) + BX (aq)    (precipitate)

We see that both reactions are double-replacements ones and from the first reaction we have the information that AY and BX are soluble in water. In the second reaction we have AZ and BX as products. Knowing from the first reaction that BX is soluble we deduce that AZ is a precipitate.
