Potassium manganate (K_(2)MnO_(4)) is formed when:

In the preparation of KMnO_4 , Pyrolusite (MnO_2) is first converted to potassium manganate (K_2MnO_4) . In this conversion the oxidation state of manganese changes from

Explain by giving suitable reason. (a). Yellow coloured aqueous solution of sodium chromate changes to orange-red when CO_2 under pressure is passed. (b). Green solution of potassium manganate, K_2MnO_4 , turns purple when CO_2 is circulated. (c). Hg^(2+) and Hg_2^(2+) salts are colourless. (d). Cu^(2+) salts are paramagnetic while Cu^(o+) salts are diamagnetic in nature.

Postassium permanganate is manufactured a large scale by fusing - with KOH and KNO_(3) to form K_(2)MnO_(4) , which is than electrolytically oxidized in an alkaline medium.

Given below are two statements : Statement I : Potassium permanganate on heating at 500K forms potassium manganate. Statement II : Both potasium permanganate and potassium manganate are tetrahedral and paramaganetic in nature. In the light of the above statement, choose the most appropriate answer from the options given below :
