Question

Consider that CuO(s) + H2SO4(aq) reacts to give CuSO4(aq), and CuO(s) + K2SO4 does not give a product. Which of the following statements explains why this is true?

A) CuO is a Strong Acid
B) H2SO4 is a Reducing Agent
C) CuSO4 is Insoluble
D) K2SO4 is Inert in this Reaction

Answer 1

CuO(s) + H2SO4(aq) reacts because H2SO4 is able to provide H+ ions, which react with CuO to form CuSO4. On the other hand, K2SO4 does not give a product because it does not supply any reactive ions to react with CuO. Therefore, K2SO4 is considered inert in this reaction.

Step-by-step explanation:

The statement that explains why CuO(s) + H2SO4(aq) reacts to give CuSO4(aq), while CuO(s) + K2SO4 does not give a product, is:

D) K2SO4 is inert in this reaction.

CuO(s) + H2SO4(aq) reacts because H2SO4 is able to provide H+ ions, which react with CuO to form CuSO4. On the other hand, K2SO4 does not give a product because it does not supply any reactive ions to react with CuO. Therefore, K2SO4 is considered inert in this reaction.
