K has an oxidation number of +1

O has an oxidation number of (-2) x 4

So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero.

Therefore, the oxidation number for Mn is +7

In KMnO4, the oxidation number of potassium (K) is +1, the oxidation number of oxygen (O) is -2, and the overall molecule has a charge of 0. To find the oxidation number of manganese (Mn), we use the formula:

(oxidation number of K) + (oxidation number of Mn) + 4*(oxidation number of O) = 0.

This gives us: 1 + x + 4*(-2) = 0. Solving for x, the oxidation number of Mn in KMnO4 is +7.

What is the oxidation number for oxygen in KMnO4?

The oxidation number for oxygen in KMnO4 is -2. The total oxidation number for the compound must equal zero (since it is neutral), and since the oxidation number for potassium (K) is +1 and for manganese (Mn) is +7, the oxidation number for oxygen must be -2 to balance the charges.


What isThe oxidation number of mn in kmno4?

The oxidation number of Mn in KMnO4 is +7. This is because oxygen (O) is typically assigned a -2 oxidation state, with the total oxidation state of the compound being 0. By following the rule that the sum of oxidation states in a compound is equal to the charge of the compound, we find that Mn is in the +7 oxidation state in KMnO4.

What is the oxidation number of Mn in K2Mno4?

The oxidation number of Mn in KMnO4 is +7. This can be determined by assigning the known oxidation numbers of potassium (+1) and oxygen (-2) and solving for the unknown oxidation number of manganese.


How do you calculate the the oxidation number of mn in k2mno4?

To calculate the oxidation number of Mn in KMnO4, set up an equation using the known oxidation numbers of potassium (+1) and oxygen (-2). Since KMnO4 is a neutral compound, the sum of the oxidation numbers must equal zero. Thus, the oxidation number of Mn can be calculated by solving the equation: 2(+1) + x + 4(-2) = 0, where x represents the oxidation number of Mn. Solving for x gives Mn a +7 oxidation number.


What is the oxidation number of manganese in KMnO4?

The oxidation number of manganese in KMnO₄ is +7. Manganese has an oxidation number of +7 in this compound because oxygen has an oxidation number of -2, and the overall charge of the permanganate ion is -1, so the sum of the oxidation numbers must equal -1.
