Question

Why Fe3+is most common form of iron present in earth crust

Answer 1

Answer:

Fe3+ (ferric ions) are the most common form of iron present in earth crust because iron is abundant on earth. They also easily oxidized as it reacts readily with oxygen and water. During the collapse of a supernova in early history of our planet, there was a production by fusion in high-mass stars and iron is scattered into space.
