Answer:
Solution :
(mixed oxide of
<br> As the oxidation state of
increases, the electronegativity value of the central metal ions increase. As a result of this difference in the electronegativity value between metals and oxygen decrease. So the acidic character increase as given below. <br>
The different oxides of Manganese are as follows:
Oxidation states of Manganese in all the above oxides are as follows :
Always remember the Thumb Rule:
Hence, Permanganate ion (Mn2O7) will have highest acidity followed by manganese trioxide followed by manganese dioxide, dimanganese trioxide and finally manganese monoxide.
