Question

In each of the followng reactions, indicate the species oxidised, the species reduced, the oxidising agent, and the reducing agent.

(a) 2Na₂S₂O₃ + I₂ → 2NaI + Na₂S₄O₆

(b) 2FeCl₃ + H₂S → 2FeCl₂ + S + 2HCl

(c) 3Mg + N₂ → Mg₃N₂

(d) AgCN + CN^- → [Ag(CN)₂]^-

(e) 3Na₂O₂ + Cr₂O₃ → 2Na₂CrO₄ + Na₂O

(f) H₂O₂ + Ag₂O → 2Ag + H₂O

Answer 1

	Oxidising agent(Species reduced)	Reducing agent (Species oxidised)
(a)	I2	Na2S2O3
(b)	FeCl3	H2S
(c)	N2	Mg
(d)	None	None (It is not a redox reaction)
(e)	Na2O2	Cr2O3
(f)	Ag2O	H2O2
