A) \[KMn{{O}_{4}}\]
B) \[HMn{{O}_{4}}\]
C) \[Pb{{(Mn{{O}_{4}})}_{2}}\]
D) \[PbMn{{O}_{4}}\]
Correct Answer: B
Solution :
On boiling red lead or lead dioxide with conc. \[HN{{O}_{3}},\] they form per manganic acid due to which a deep pink colour is developed. \[2M{{n}^{2+}}+5Pb{{O}_{2}}+4{{H}^{+}}\xrightarrow{{}}2MnO_{4}^{-}\] \[+5P{{b}^{2+}}+2{{H}_{2}}O\] \[2MnC{{l}_{2}}+3{{H}_{2}}O+5O\xrightarrow{{}}2HMn{{O}_{4}}+4HCl\]You need to login to perform this action.
