Question

In the reaction : PbS(s) + H2O2(aq) → PbSO4(s) + 4H2O( l )

Identify the substance oxidised and the substance reduced.​

Answer 1

Answer:

Substance oxidised: PbS

Substance Reduced: H2O2

Explanation:

O2 is added in Pbs. Therefore it is the substance oxidised. H2O2 is giving O2. Therefore it is the substance reduced

Answer 2

Dear your answer is

PbS + H202 ➡️ PbSO4 + H2O

Oxidised = PbS

Reduced = H202
