Solution

Solution Steps

Step 1: Identify the Chemical Formula of Copper(II) Sulfate

Copper(II) sulfate is commonly represented by the chemical formula $\text{CuSO}_4$. This compound consists of copper (Cu), sulfur (S), and oxygen (O).

Step 2: Determine the Ions in Copper(II) Sulfate

Copper(II) sulfate dissociates in water to form ions. The copper ion in this compound is typically in the +2 oxidation state, represented as $\text{Cu}^{2+}$. The sulfate ion is a polyatomic ion with the formula $\text{SO}_4^{2-}$.

Step 3: Match the Ions to the Given Options

From the dissociation of $\text{CuSO}_4$, the ions formed are $\text{Cu}^{2+}$ and $\text{SO}_4^{2-}$. Comparing these ions with the given options, the correct pair is $\text{Cu}^{2+}$ and $\text{SO}_4^{2-}$.

Final Answer

\[ \boxed{\text{Cu}^{2+} \text{ and } \text{SO}_4^{2-}} \]
