A) Fe and Zn
B) Fe and Pt
C) Pb, Ag and Pt
D) Fe, Ag and Pt
E) Fe, Zn and Pt
Correct Answer: B
Solution :
Fe and Pt metals do not give a metal nitrate on treatment with concentrated \[HN{{O}_{3}}\] because Pt have no reaction with\[HN{{O}_{3}}\]of any concentration and Fe becomes passive on treatment with highly concentrated\[HN{{O}_{3}}\]. It is due to the deposition of oxide layer on the metal surface.You need to login to perform this action.
