State with equations, what happens when :
(10) Al is heated with MgO at temperature- (i) 1623 K and (ii) above 1623 K.

Text Solution

Verified by Experts

At temperatures below 1623K, Al cannot reduce MgO to Mg. However, at temperature above 1623 K, Al reduces MgO to Mg and itself is oxidised to `Al_(2)O_(3)`.
