H2SO4 IS A OXIDISING AGENT, H2S IS A REDUCING AGENT, WHIL SO2 IS A REDUCING AGENT.EXPLAIN

H₂SO₄

Hot concentrated sulphuric acid is a moderately strong oxidising agent. In this respect, it is intermediate between phosphoric and nitric acids. Both metals and non-metals are oxidised by concentrated sulphuric acid, which is reduced to SO₂.

Cu + 2 H₂SO₄(conc.) → CuSO₄ + SO₂ + 2H₂O

3S + 2H2SO4(conc.) → 3SO2 + 2H2O

C + 2H₂SO₄(conc.) → CO₂ + 2 SO₂ + 2 H₂O

H₂S

It is a reducing agent since it can be oxidised easily into to sulphur

SO₂ 

It is a reducing agent since it can be also oxidised easily into to SO₃
