Molecular and Net Ionic Equation

Question

What is the type of reaction when sulfuric acid is added to the black CuO(s)?

Write a molecular equation and a net ionic equation for the reaction to support your answer.

What are the spectator ions?

Answer 1

Sulfuric acid = H₂SO₄

When H₂SO₄ reacts with CuO(s), we have the following molecular equation:

H₂SO₄(aq) + CuO(s) ==> CuSO₄(aq) + H₂O(l)

The ionic equation is:

2H⁺(aq) + SO₄^2-(aq) + CuO(s) ==> Cu²⁺(aq) + SO₄^2-(aq) + H₂O(l)

Net ionic equiation is:

2H⁺(aq) + CuO(s) ==> Cu²⁺(aq) + H₂O(l)
