    2. Answer the following.

    vii. What is the oxidation state of S in H2SO4.

    Answer:-

    (Oxidation number of H) + (Oxidation number of S) + (Oxidation number of O) = 0

    2 × (+1) + (Oxidation number of S) + 4 × (- 2) = 0

    Oxidation number of S + 2 – 8 = 0

    Hence, oxidation number of ‘S’ in H2SO4 = +6
