    Chemistry Doubts: IGCSE Paper 3

    It does! but it doesn't help alot.. all you need to know is how electrons flow from the negative terminal to the iron preventing it from ionising/ rusting

    chemistry p3 IGCSE !! (some important points)

    All you need to know is that oxygen is blown into the furnace (which is full of pig iron) so it reacts with the carbon (impurity) producing CO2... Oxygen is blown into the furnace until only 1% carbon remains.
