8H+ + MnO4- + 5Fe2+--> 5Fe3+ + Mn2+ + 4H20
Roman numerals are typically used in compound names to indicate the oxidation state of an element. This is necessary when the element can have multiple oxidation states and is written as a cation in the compound. For example, iron can exist in the +2 or +3 oxidation state, so the compound name "iron(II) chloride" specifies that it is the +2 oxidation state of iron.
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
Formula: Fe2+
Iron(II) chromate is a chemical compound with the formula FeCrO4. It is a yellow solid that is sparingly soluble in water. The compound is used in analytical chemistry applications as an indicator for the titration of lead.
The compound formula for ferric sulfate is Fe2(SO4)3.
Formula: Fe2+
The electron configuration of Fe2+ is 1s2 2s2 2p6 3s2 3p6 3d6. Fe2+ has lost two electrons from its neutral Fe atom configuration.
The chemical formula for NO3 is nitrate, and the chemical formula for Fe2 is iron(II) or ferrous ion.
Fe2+Nb2O6
The formula for iron(III) sulfate is Fe2(SO4)3.
The formula for ferric chromate is Fe2(CrO4)3.
The chemical formula Fe2(SO4)3 corresponds to Iron(III) sulfate, also known as ferric sulfate.
Iron(III) Sulfate = Fe2(SO4)3
