An example of redox reaction

An example of redox reaction

Options

(a) AgNO₃ + NaCl → AgCl + NaNO₃
(b) CuSO₄ + 4NH₃ → Cu(NH₃)₄ SO₄
(c) H₂ + Cl₂ → 2HCl
(d) KNO₃ + NaCl → KCl + NaNO₃

Correct Answer:

H₂ + Cl₂ → 2HCl

Explanation:

H₂ + Cl₂ → 2HCl. H₂ (oxidation state = 0 ) changes to H⁺ (oxidation state = +1) and Cl₂ (oxidation state = 0) changes to Cl⁻ (oxidation state = -1). So H₂ has been oxidised and Cl₂ has been reduced, making this is redoxreaction.
