Question

Pb on reaction with conc. $HN{O}_3$ gives

• A. $Pb{\left(N{O}_3\right)}_4+N{O}_3$
• B. $Pb{\left(N{O}_3\right)}_3+N_{2}O$
• C. $Pb{\left(N{O}_3\right)}_2+N{O}_2$
• D. $PbN{O}_3+NO$

Answer 1

Answer: (C)

$HN{O}_3$ is the best solvent for lead and the reaction is as follows

$Pb+4HN{O}_3(conc.)\to Pb{\left(N{O}_3\right)}_2+2N{O}_2+2H_{2}O$
