Answer #1

Oxidation number of each element in reactant is

Mn=0

Ag=+1

Oxidation number of each element in product is

Mn=+2

Ag=0

Mn in Mn has oxidation state of 0

Mn in Mn+2 has oxidation state of +2

So, Mn is oxidised to Mn+2

Ag in Ag+ has oxidation state of +1

Ag in Ag has oxidation state of 0

So, Ag in Ag+ is reduced to Ag

species oxidized : Mn species reduced: Ag+

oxidizing agent: Ag+ reducing agent: Mn

As the reaction proceeds, electrons are transferred from Mn to Ag
