Question

Pb on reaction with conc. $HNO_{3}$ gives

• A. $Pb\left(\right.NO_{3}\left(\left.\right)_{4}+NO_{3}$
• B. $Pb\left(\right.NO_{3}\left(\left.\right)_{3}+N_{2}O$
• C. $Pb\left(\right.NO_{3}\left(\left.\right)_{2}+NO_{2}$
• D. $PbNO_{3}+NO$

Answer 1

Answer: (C)

$HNO_{3}$ is the best solvent for lead and the reaction is as follows
$Pb+4HNO_{3}\left(\right.conc.\left.\right) \rightarrow Pb\left(\right.NO_{3}\left(\left.\right)_{2}+2NO_{2}+2H_{2}O$
