Answer 2

Here is your answer

1.All metals don't corrode because some metal found in native states like gold,etc.

2.we can't keep sulphate solution in aluminium vessel Due to amphoteric nature of Aluminium, there is a reaction between Al and alkalis. 

3.because metals cannot be extracted from minerals in a convenient way.
E.g.:- Aluminum metal is found in both minerals: clay and bauxite.
