Which of the following is an oxidation-reduction reaction? so2(g) h2o(l) right arrow. h2so3(aq) caco3(s) right arrow. cao(s) co2(g) ca(oh)2(s) h2co3(l) right arrow. caco3(aq) 2h2o(l) c6h12o6(s) 6o2(g) right arrow. 6co2(g) 6h2o(l)

Sagot :

The reaction which shows oxidation and reduction simultaneously is C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l).

What are redox reactions?

Those reaction in which oxidation as well as reduction of substances takes place simultaneously will known as redox reactions.

  • SO₂(g) + H₂O(l) → H₂SO₃(aq)
  • CaCO₃(aq) → CaO(s) + CO₂(g)
  • Ca(OH)₂(s) + H₂CO₃(l)  CaCO₃(aq) + 2H₂O(l)

Above reaction are not the redox reactions as in these reaction oxidation and reduction simultaneously not takes place.

  • C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l)

In the above reaction reduction of oxygen takes place as its oxidation state changes from 0 to -2, and at the same time oxidation of carbon takes place as its oxidation state changes from 0 to +4.

Hence correct option is (4).
