Oxi dation means addition of oxgen ,Removal of hydrogen.
HCl+MnO4 ---->
Manganese has oxidation states from +7 to -3. In elemental state it is oxidation state 0.
The oxidation number of Mn in manganese VII oxide is +7.
Manganese oxidation state = +7 So, it is also called Manganate(VII)
The oxidation number of manganese in KMnO4 is 7+.
Manganese is a metal element. It shows the largest oxidation number.
Manganese has oxidation states from +7 to -3. In elemental state it is oxidation state 0.
The common oxidation number of manganese are +2, +4 and +7.
The oxidation number of Mn in manganese VII oxide is +7.
Manganese oxidation state = +7 So, it is also called Manganate(VII)
The oxidation number of manganese in KMnO4 is 7+.
Manganese is a metal element. It shows the largest oxidation number.
MnO2 manganese(IV) oxide. Oxygen has a -2 oxidation state (oxidation state is a better term here as oxidation number is better used for complexes- they give the same answer for this compound)
+6 for Mn
+2
The most common oxidative states of manganese are +2, +3, +4, +6, and +7.
manganese is a 3d element. +2 is the oxidation number in this ion.
I assume you mean the oxidation number of Mn in the permanganate ion , MnO4- The sum of the oxidation numbers is the charge on a polyatomic ion so Mn has an oxidation number of +7 as each O is assigned -2.
