B) forms \[F{{e}_{2}}{{O}_{3}}.x{{H}_{2}}O\] on the surface
C) forms iron phosphate film
D) forms ferric hydroxide
Correct Answer: A
Solution :
In electrochemical series, iron is placed below sodium, so it cannot displace sodium from its salt solution. Hence, no reaction takes place. \[Fe+N{{a}_{3}}P{{O}_{4}}\xrightarrow{{}}No\,\,reaction\]You need to login to perform this action.
