Explain why a green solution of potassium manganate turns purple and a brown solid is precipitated when `CO_(2)` gas is bubbled into the solution.

When we pass carbon dioxide gas through a green coloured solution of potassium manganate, the colour of solution changes to purple and a brown coloured solid gets precipitated. The green colour of potassium manganate solution also becomes purple when it is subjected to electrolysis using iron electrodes. In following reaction 3 K_2 underset("(green)")(MnO_4 + 2H_2 O + 4CO_2 to underset("(purple)")(2KmnO_4 )+MnO_2 + 4KHCO_3 the function of CO_2 is

When we pass carbon dioxide gas through a green coloured solution of potassium manganate, the colour of solution changes to purple and a brown coloured solid gets precipitated. The green colour of potassium manganate solution also becomes purple when it is subjected to electrolysis using iron electrodes. In the brown solid precipitate, oxidation state of Mn is

When we pass carbon dioxide gas through a green coloured solution of potassium manganate, the colour of solution changes to purple and a brown coloured solid gets precipitated. The green colour of potassium manganate solution also becomes purple when it is subjected to electrolysis using iron electrodes. The change of colour from green to purple is due to

What happens when: CO_2 gas is bubbled through green solution of K_2MnO_4 .

If CO_(2) is passed through a green aqueous solution of potassium manganate, the solution turns violet and gives a brown precipitate. Explain.

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.

Anhydrous white solid (A) on addition of potassium iodine solution gave a brown precipitate which turned white (B) on addition of excees of hypo solution. When potasium cyanide is added to an aqeous Solution of (A) a white precipitate is formed which then dissolved in excess forming (C ) A Solution (%) of (A) on adding to a solution of white portion of egg produced violet colouration in alkaline medium (i.e) in presence of NaOH) identify compound (A) and explain the reactions.
