Identify the oxidation states of Mn when `MnO_3^(3-)` ion undergoes disproportionation reaction under acidic medium

The oxidation state of Mn in MnO_4^(2-) is

Which of the following substances undergo(s) disproportionation reactions under basic medium?

Oxidation state exhibited by Mn in MnO_(2) is

Give the disproportionation reaction of H_3PO_3 .

Oxidation state exhibited by Mn in MnO_(4)^(2-) is

(a) What happens when (i) Manganate ions (MnO_(4)^(2-)) undergoes disproportionation reaction in acidic medium ? (ii) Lanthanum is heated with Sulphur? (b) Explain the following trends in the properties of the members of the First series of transition elements: (i) E^(@) (M^(2+)//M) value for copper is positive (+ 0.34 V) in contrast to the other members of the series. (ii) Cr^(2+) is reducing while Mn^(3+) is oxidising, though both have d^(4) configuration. (iii) The oxidising power in the series increases in the order VO_(2)^(+) lt Cr_(2)O_(7)^(2-) lt MnO_94)^(-) .

Write the disproportionation reaction of H_(3)PO_(3)

MnO_(4)^(2-) undergoes disproportionation reaction in acidic medium but MnO_(4)^(-) does not. Given reason.

Oxidation reaction involves loss of electrons, and reduction reaction involves gain of electrons. The reaction in which a species disproportinates into two oxidation states ( lower and higher) is called disproportionation reaction. Which of the following is not a dispropotional reaction?

Oxidation reaction involves loss of electrons, and reduction reaction involves gain of electrons. The reaction in which a species disproportinates into two oxidation states ( lower and higher) is called disproportionation reaction. Which of the following statements is wrong?
