Oxidised:
H
2
S
The oxidation number of S increases from -2 to 0. Thus, S itself is oxidised and acts as reducing agent.
Reduced:
F
e
C
l
3
The oxidation number of Fe decreases from +3 to +2. Thus, Fe itself is reduced and acts as oxidising agent.
Note:
Any species that is oxidised acts as reducing agent.
Any species that is reduced acts as oxidising agent.
