For MnO2+KOH+O2→Δ2K2MnO4+4H2OMn{O_2} + KOH + {O_2}\xrightarrow{\Delta }2{K_2}Mn{O_4} + 4{H_2}O
If true enter 11 else 00.

Explanation

Solution

It is of the +6 + 6 oxidation state of the permanganate ion. In a strongly basic solution, the permanganate (VII) is reduced to the +6 + 6 oxidation state. It produces a green color.

Complete step by step answer:
In compounds, manganese remains with a number of different oxidation states. It can be easily raised to the +2 + 2 state. For example, by reaction with hydrochloric acid (HCl)\left( {HCl} \right) to form manganous chloride, MnCl2MnC{l_2}. Manganese can also be found in the +3 + 3 (manganic) oxidation state. But this oxidation state is unstable. It usually goes back to the +2 + 2 oxidation state. Both of these manganous and manganic ions can form acidic solutions. Manganese is actually found largely in the +4 + 4 oxidation state in manganese dioxide (MnO2)\left( {Mn{O_2}} \right). The +4 + 4 oxidation state is amphoteric, which means in the +4 + 4 oxidation state manganese can either donate or accept electrons in any chemical reactions. Manganese also exists in +6 + 6 and +7 + 7 oxidation states. The +6 + 6 oxidation state is found largely in the manganate ion (MnO4−)\left( {MnO_4^ - } \right) and the +7 + 7 oxidation state is found largely in the permanganate ion (MnO4−)\left( {MnO_4^ - } \right). These two ions are stable in basic solutions.
In a strongly basic solution, we can also see that the permanganate (VII) is reduced to the (green) +6 + 6 oxidation state of the manganate ion (MnO24−)\left( {MnO_2^{4 - }} \right):
MnO4−+e−→MnO24−Mn{O^{4 - }} + {e^ - } \to MnO_2^{4 - }
Here, KOHKOH is the basic medium. So, when MnO2Mn{O_2} reacts with KOHKOH in the presence of O2{O_2}, potassium permanganate (K2MnO4)\left( {{K_2}Mn{O_4}} \right) (green colored) is obtained. The required reaction is:
2MnO2+4KOH+O2→2K2MnO4+2H2O2Mn{O_2} + 4KOH + {O_2} \to 2{K_2}Mn{O_4} + 2{H_2}O
So, it is true.

Note: Manganese can be found in abundance in nature. We should remember that manganese can also be found in +1 + 1 oxidation state (in the case of complex cyanide). Also, we should remember that manganese is not very stable in its +5 + 5 oxidation state in basic solution.
