Explanation:

Step1: Determine ion charges

Copper(I) has a charge of \( +1 \) (\( \text{Cu}^+ \)), sulfate ion is \( \text{SO}_4^{2-} \).

Step2: Balance charges

To balance the charges, we need 2 \( \text{Cu}^+ \) ions (total \( +2 \)) to balance 1 \( \text{SO}_4^{2-} \) ion (total \( -2 \)).

Step3: Write the formula

Combine the ions: \( \text{Cu}_2\text{SO}_4 \).

Answer:

\( \text{Cu}_2\text{SO}_4 \)
