Advanced Higher Chemistry 9 Oxidation numbers and Dative bonds ed

An apparently random look at two concepts which seem unconnected with anything. However, you need them for the next lesson so I thought I'd do a stand-alone video on them: Oxidation states/numbers and Dative bonds [SQA p59 Scholar p38, 56-59]

Remember all the way back to N5, where we learned that ammonia molecules can neutralise acids? And we all just accepted that, despite how different ammonia was to the other three bases? This video explains how that is possible.
