A

 

[Mohamed123456789]

which one was oxidised A OR b ?

B because it was the negative electrode which means that electrons were lost from Fe to change to fe3+ which will form rust (fe2o3)

 

[Ahmed Khider]

even i rote A,although others said it was B

It can never be b..oxygen was passed through electrode A n therefore the iron in this electrode will react with oxygen!!!!!!!!Dnt lsn to anyone who says its b..the answer is obvious its A!!!!!!!!!!!!!
