A student made the following observations in the laboratory, i) Clean copper metal did not react with 1 molar ${\rm{Pb}}{\left( {{\rm{N}}{{\rm{O}}_3}} \right)_2}$ solution. ii) Clean lead metal dissolved in a 1 molar ${\rm{AgN}}{{\rm{O}}_3}$ solution and crystals of ${\rm{Ag}}$ metal appeared. iii) Clean silver metal did not react with 1 molar ${\rm{Cu}}{\left( {{\rm{N}}{{\rm{O}}_3}} \right)_2}$ solution. The order of decreasing reducing character of the three metals is :

${\rm{Pb}},{\rm{Cu}},{\rm{Ag}}$

${\rm{Cu}},{\rm{Pb}},{\rm{Ag}}$

${\rm{Cu}},{\rm{Ag}},{\rm{Pb}}$

${\rm{Pb}},{\rm{Ag}},{\rm{Cu}}$

A student made the following observations in the laboratory,
i) Clean copper metal did not react with 1 molar

\mathrm{Pb}{\left( {\mathrm{N}{\mathrm{O}_3}} \right)_2}

solution.
ii) Clean lead metal dissolved in a 1 molar

\mathrm{AgN}{\mathrm{O}_3}

solution and crystals of

\mathrm{Ag}

metal appeared.
iii) Clean silver metal did not react with 1 molar

\mathrm{Cu}{\left( {\mathrm{N}{\mathrm{O}_3}} \right)_2}

solution.
The order of decreasing reducing character of the three metals is :

View answer and explanation

Correct option: C

\mathrm{Pb},\mathrm{Cu},\mathrm{Ag}

Option C (

\mathrm{Pb},\mathrm{Cu},\mathrm{Ag}

) is correct because Pb dissolved in AgNO3, Cu did not react with Pb(NO3)2, and Ag did not react with Cu(NO3)2, indicating the order of reducing character.
