Essential Chemistry for IGCSE - Metals And Reactivity (Section 5 - No. 31)
How does the protective layer of aluminum oxide on aluminum affect its reactivity?
It increases reactivity.
It has no effect on reactivity.
It prevents further reaction, thus decreasing reactivity.
It makes the aluminum more conductive.
Explanation
The oxide layer forms a barrier, preventing further reaction and thus decreasing reactivity.
