Question

Which two species are the anions in copper sulphate solution?

• A. Hydrogen ion and sulphate ion
• B. Copper ion and sulphate ion
• C. Copper ion and hydrogen ion
• D. Sulphate ion and hydroxide ion

Answer 1

The correct option is C Copper ion and hydrogen ion

When copper sulphate is subjected to electrolysis, the solution dissociates into sulphate$\left(S{O}_4^{-2}\right)$ and hydroxide ion $\left(O{H}^{-}\right)$ anions. These two anions present in copper sulphate solution migrate towards anode.
