Complex ions are not the only ions that have color in solution. For example, Cu2+ is blue in aqueous solutions but is not a complex ion.
That's correct, but you haven't answer the question. Mn and Cu are transition metals that have d-orbitals available. One of the properties of the d-orbitals is that they can unfold and allow electrons to move freely in those unfolded orbitals. The energy the electrons lose is in the visible range of the spectrum, so we see it as colour.

How can write formula of manganese II superoxide?
Molecular: Mn(O2)2empirical: MnO4
What are the oxidation numbers of the atoms in the MnO4- ion?
+7 for Mn -2 for each O
What is the oxidation number of MnO4?
O.S. of Mn = +7 O.S. of O = -2 O.N. of cpd = -1
What is the oxidation numbers of manganese in MnO4 1-?
The oxidation number of manganese in KMnO4 is 7+.
What colour change occurs when h2o2 is added to kmno4?
MnO4- turns into Mn+2.So purple change into pale pink.
What is the oxidation number for MnO4-2?
manganese is a metal element. It shows +4 in Mno4 ompouund.
Why the colour of KMnO4 is purple even though Mn exhibit plus 7 oxidation state?
its MnO4 that gives purple colour to the KMnO4 solution. MnO4 absorbs all the six colours present in the white light except for indigo and this colour reflects back to our eyes that is why we see it as purple coloured solution.
What is the symbol for cupric sulfate?
Permanganate is a poly atomic ion, not an element. It contains two elements: manganese (Mn) and oxygen (O). The formula of the permanganate ion is MnO4-

How are the oxygen atoms balanced for the red-ox equations in acidic solutions?
To balance the oxygens, you add H2O to one side, and the H^+ to the other (acid). Example:MnO4^- ===> Mn^2+ add 4 H2O to the right side MnO4^- ===> Mn^2+ + 4H2O this balances the oxygens. Now add 8H^+ to the left side MnO4^- + 8H^+ ===> Mn^2+ + 4H2O Now this is balanced for Mn, H and O. You now only have to balance the electrons (charge).
What is the oxidation numbers of manganese in MnO4 1-?
The oxidation number of manganese in KMnO4 is 7+.
What colour change occurs when h2o2 is added to kmno4?
MnO4- turns into Mn+2.So purple change into pale pink.
What is the oxidation number in MnO4?
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
What is the oxidation number of Mn in Mn04?
In the anions of oxyacids, oxygen is always assigned an oxidation number of -2. Therefore, in an MnO4-1 anion, manganese must have an oxidation number of +7 to achieve electrical balance for the anion. (There is no neutral compound with the formula MnO4.)
What is the formula for Hydronium permanganate?
The chemical formula of potassium permanganate is KMnO4.
