    Can somebody explain how the loss of a hydrogen ion is oxidation? It's really confusing me in terms of oil rig

    Alternative definitions of redox are:

    oxidation = addition of oxygen or removal of hydrogen.
    reduction = removal of oxygen or addition of hydrogen.

    These definitions are useful in the realm of organic chemistry where it may be difficult to count up all of the oxidation numbers.

    I admit that the use of the term hydrogen 'ion' in the subsequent step is somewhat confusing.

    Could you explain how the addition/loss of hydrogen actually results in a change in oxidation state? Sorry if that's a difficult question I just like to really understand how something works

    It's an empirical rule.

    If you take (for example) methanol, CH3OH, and work out the oxidation state of the carbon atom (-2) ...

    ... and then oxidise it to methanal, CH2O, you have removed two hydrogen atoms and the oxidation state of the carbon atom is now zero.

    Hence removal of hydrogen has resulted in the oxidation of the carbon atom.

    If methanal is now oxidised to methanoic acid, HCOOH, the new oxidation state of the carbon atom is +2.

    Hence addition of oxygen has resulted in oxidation of the carbon atom.
