window frames made from iron corrode faster than made from aluminium . EXPLAIN
rnexperts help pls
Dear student!
Aluminum is more reactive than iron, so theoretically it should corrode faster and it corrodes faster than Iron but, after corrosion it forms an aluminum oxide(Al2O3) with oxygen which is very thin layer and covers the whole surface of aluminum and hence, it resists the rest of the aluminum to corrode , and so it does not corrodes as much as the iron sheet frame!
