8.36 (i) The chromite ore (FeCr₂O₄) is fused with sodium hydroxide (NaOH)

4FeCr₂O₄ +16 NaOH+ 7O₂ → 8Na₂CrO₄ +2Fe₂O₃ +8H₂O

The yellow solution of sodium chromate is then filtered and acidified with sulphuric acid giving its dichromate.

2Na₂CrO₄ +H₂SO₄→ Na₂Cr₂O₇ + Na₂SO₄ +H₂O

On cooling, sodium sulphate crystallizes out as Na₂SO₄.10H₂O and is removed.

Na₂Cr₂O₇ +2KCl → K₂Cr₂O₇ + 2NaCl

(ii) The pyrolusite ore(MnO₂) is oxidised in the presence of potassium hydroxide by heating.

2MnO₂ + 4KOH +O₂→ 2K₂MnO₄ + 2H₂O

The green potassium manganate (K₂MnO₄) is then treated with a current of chlorine or ozone to oxidise potassium manganate to potassium permanganate.

2K₂MnO₄ +Cl₂→ 2KCl +2KMnO₄

K₂MnO₄ +O₃ +H₂O → 2KMnO₄ +2KOH +O₂

8.31 (i) Of the d4 species, Cr²⁺ is strongly reducing while manganese (III) is strongly oxidizing: The +2 oxidation state becomes more stable on moving across a period i.e. the tendency of metals to give electrons becomes more. Therefore, vanadium(II) oxide and chromium(II) oxide are strong reducing agents.

As if the value of electrode potential is higher i.e. more energy required to withdraw an electron from an isolated atom, more readily it can be reduced and lesser the electrode potential more readily it can be oxidized.

The electrode potential of Cr³⁺? Cr²⁺is negative so it acts reducing agent or can undergo oxidation which makes it a more stable ion while that of Mn³⁺? Mn²⁺ is positive and it undergoes reduction acts as strong oxidizing agent. Also, Mn³⁺ has an exactly half-filled d- orbital which is highly stable.

(ii) Cobalt(II) is stable in aqueous solution but in the presence of complexing reagents, it is easily oxidized: Cobalt gets oxidized from +2 to +3 oxidation state in the presence of complexing reagents.

(iii) The d¹ configuration is very unstable in ions:The d¹ electron can be easily lost after the loss of ns electrons. Therefore, the elements having d¹ configuration undergo disproportionation reactions.
