Question

Select one correct statement: A) Specific ions are necessary for metals and alloys.B) An environment that causes SCC of one alloy would also causes SCC of another alloy.C) As specific ions form a film on the metal surface, hence, those ions which form films may be adequate to cause SCC.

Answer 1

Answer:

option  C

Explanation:

The correct statement is As specific ions form a film on the metal surface, hence those ions which form films may be adequate to cause SCC

other options are wrong as ; specific ions are not necessary for metals and alloys and also an environment causing SCC for an alloy might not cause SCC of another alloy found in the environment
