Both #FeCl_2# and #Na_2SO_3# can act as reducing agents


Oxidation is loss of electrons. Reduction is gain of electrons.

An oxidising agent takes in electrons. A reducing agent gives them out.

Both ozone and chlorine are powerful oxidising agents.

Iron(II) choride can lose electrons to form iron(III):


A solution of iron(II) chloride will slowly oxidise to iron(III) in the presence of air.

Sodium sulfite is also a reducing agent:


It is used as an anti - oxidant in food preservation.
