Question 10
H

Why can attaching copper to iron increase corrosion of the iron?

[1]
A

Iron is more reactive and is preferentially oxidised

B

Copper is oxidised instead of the iron

C

Iron is less reactive than copper, so it is oxidised first

D

Copper forms an alloy with the iron that rusts faster
