Using oxidation states In naming compounds You will have come across names like iron(II) sulphate and iron(III) chloride.

The (II) and (III) are the oxidation states of the iron in the two compounds: 2 and 3 respectively.

Something else in the reaction must be losing those electrons. The oxidation state of the molybdenum is increasing by 4.

Any oxidation state fall by one substance must be accompanied by an equal oxidation state increase by something else. That means that the oxidation state of the cerium must fall by 4 to compensate.

It would probably be best to read on and come back to these links if you feel you need to.

We are going to look at some examples from vanadium chemistry.

That tells you that they contain Fe In each of the following examples, we have to decide whether the reaction involves redox, and if so what has been oxidised and what reduced.

Example 1: This is the reaction between magnesium and hydrochloric acid or hydrogen chloride gas: Have the oxidation states of anything changed?

You can't actually do that with vanadium, but you can with an element like sulphur. Summary Oxidation state shows the total number of electrons which have been removed from an element (a positive oxidation state) or added to an element (a negative oxidation state) to get to its present state.

Recognising this simple pattern is the single most important thing about the concept of oxidation states.
