Question:
(a) Account for the following:
(i) Cu+ is unstable in an aqueous solution.
(ii) Transition metals form complex compounds.
(b) Complete the following equations:
Cr₂O₇²⁻ + 8H⁺ + 3NO₂⁻ →
Solution:
(a)(i) Cu⁺ gets oxidized in aqueous solution to get stable configuration Cu²⁺
(ii) Since, transition metals have unfilled or partially filled d-orbital thus, to satisfy its octate it forms complex compounds
(b) Cr₂O₇²⁻ + 8H⁺ + 3NO₂⁻ → 2Cr³⁺ + 4H₂O + 3NO₃⁻
