b. Write the electronic concept for oxidaton and reduction

Question

A redex reaction involves simultaneous oxidation and reduction half reaction.
a. Identify the oxidising and reducing agents in the following reaction.
H2SO4 + 2 HBr → SO2 + Br2 + 2 H2O 
b. Write the electronic concept for oxidaton and reduction

sk8teroy · Answer

$$H_{2}SO_{4}$$ is the oxidising agent. $$S^{6+}$$ is reduced to $$S^{4+}$$. $$HBr$$ is the reducing agent. $$Br^{-}$$ is oxidised to $$Br_{2}$$  (neutral charge)
