Question

aluminium gets corrodeddue to ko​

Answer 1

By nature, aluminium is a reactive metal but it is also a passive metal. It means that while nascent aluminium will react with oxygen and water in the environment, the resulting compound will form a layer on the surface protecting the material underneath from further corrosion.

Answer 2

$\huge{\boxed{\boxed{\underline{\rm{\pink{☆Answer}}}}}}$

Erosion corrosion of aluminium is caused by the impingement of a high-speed water jet on the aluminium body. Two factors that aggravate erosion-corrosion are the velocity of the water and its pH level. The existence of carbonate and silica content in water can further augment the corrosion rate.
