Considering the stability of Cu(II) and Cu(I) which of the following statements is true?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Cu(II) is more stable
In aqueous solution:
- Cu²⁺ is more stable than Cu⁺, because Cu⁺ tends to undergo disproportionation:
$2Cu^+ \rightarrow Cu^{2+} + Cu$
- The stability of Cu(I) depends on the anion and solvent, but generally Cu(II) is more stable.
