Question

In the following reaction, which species is reduced? 2k+br2 yield 2k+ + 2br-

Answer 1

The species that is reduced in

2K + Br2 = 2K^+ + 2Br^-


is Br2 is reduced

This is because Br2 move from oxidation state zero to oxidation state of negative one. K is been oxidized since it move from oxidation state zero to oxidation state of positive one. K act as a reducing agent while Br2 act as a oxidizing agent
