When do you need to use a roman numeral in the name of a compound?
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.
If zinc and iron are used to make a cell what half-reactions will occur for zn2 plus aq plus 2e- zn s e0 equals -0.76 v and for fe3 plus aq plus e- fe2 plus aq e0 equals 0.77 v?
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
