Concentrated aqueous solutions of copper (I)nitrate,sodium sulfate and silver acetate are mixed together.The precipitate which forms is ________.

Question

Quizplus · Accepted Answer

When copper (I) nitrate and sodium sulfate are mixed, no precipitate is expected as both compounds are soluble in water. However, when silver acetate is added to the mixture, a precipitation reaction occurs as silver acetate is insoluble in water.

The balanced chemical equation for the reaction is:

2AgCH3COO (aq) + Cu2(NO3)2 (aq) + Na2SO4 (aq) → Cu(CH3COO)2 (s) + 2AgNO3 (aq) + Na2(CH3COO)2 (aq) + SO4 (aq)

The solid formed is copper (I) acetate (Cu(CH3COO)2), which is a yellowish-green color. Therefore, the best choice is C), silver sulfate is not formed during this reaction.
