Question

Consider that CuO(s) + H2SO4(aq) reacts to give CuSO4(aq) and CuO(s) + K2SO4does not give a product. Which of the following statements explain why this is true? One or more statements may be true. You will receive negative points for incorrect answers. a. Potassium sulfate cannot dissolve in water since it is a salt and cannot react with CuO. b. CuO is very stable and therefore does not dissociate in water and therefore cannot react with the sulfate ion in potassium sulfate. c. Acids and bases do not react with each other. d. CuO is a basic salt and therefore reacts with sulfuric acid to give copper (II) sulfate and water. e. CuO is not soluble in water and therefore cannot react with potassium sulfate to give a salt.

Explanation / Answer

Ans b and d

CuO has a high lattice energy and is quite stable. It does not dissolve in water giving its ions, but as it is bronsted lowry base it can accept protons from acid and can form CuSO4 with H2SO4.

whereas being insoluble in water and greater activity of potassium it can not replace potassium from its salt, so the product does not form
