Why is reo4 Colourless?
The 5d orbitals of Re are at a higer energy than the 3d orbitals of Mn. This means that ligand to metal C.T, transition will appear at much higher energy for KReO4 than for KMnO4 . As the transition in KReO4 appears at the near UV we see the compound as colourless.
Why do Mn 2 compounds have pale pink?
Mn2+ in H2O is d5 high-spin. CoCl2 in water results in an octahedral [Co(H2O)6]2+ complex, which is d7 high-spin. The d→d transitions are forbidden and so the colour is pale.
Why is mno4 colored?
Permanganate ion has four oxygen atoms as ligands and the oxidation state of manganese is \[ + 7\] suggesting that the d- orbital of the central metal atom is empty. Thus, charge transfer takes place in permanganate ion and is responsible for its intense pink colour.
Is MnSO4 Colourless?
Manganese(II) sulphate is not colourless. It is a faint pink. Compare this image taken from Wikipedia , where a full list of authors is available: However, it is true that the colour is rather faint, and you need a white background to properly see it.

Why is KMnO4 intensely Coloured whereas kteo4 and kreo4 are Colourless?
The color of the Mn+4 cation is more a dirty dark yellow color. The color in KMnO4 arises from an electronic transition, but it is actually not a d-d transition, since the Mn in this compound has no d electrons.
Why are sc3+ salts Colourless?
The colour is due to d–d transition. There is one d electron present in the 3d subshell. There are no d electrons; hence, d–d transition is not possible. Hence, Sc3+ is colourless.
What is the colour of Mn 2?
Pale pink
Examples
| Name | Formula | Color |
|---|---|---|
| Monochromate | CrO 2− 4 | Yellow |
| Dichromate | Cr 2O 2− 7 | Orange |
| Manganese(II) | Mn2+ | Pale pink |
| Manganese(III) | Mn3+ | Crimson |
What is the oxidation number of MnSO4?
The oxidation number of Mn in MnSO4 is 2..
What causes the color of MnO4-?
Many transition metal compounds owe their colors to d→d transitions, but MnO4- is a d0 compound*, so that can’t explain the color. Instead, there is an excited state in which electrons transfer from the lone pairs of the oxygen back to the manganese atom. Absorption of light to produce this excited state causes the permanganate to appear colored.
What type of compound is MnSO4?
Manganese (II) sulfate (MnSO4), also known as manganese sulfuric acid anhydrous or manganese sulphate, belongs to the class of inorganic compounds known as transition metal sulfates. What is the function of MnSO4 in the reaction?
What is MnSO3?
What is MnSO3? Manganese (II) sulfate usually refers to the inorganic compound with the formula MnSO4·H2O. This pale pink deliquescent solid is a commercially significant manganese (II) salt.
