Question

Among the following nitrates, Lead nitrate, Silver nitrate and Ammonium nitrate; the one that decomposes without leaving any solid residue is

• A. Lead nitrate
• B. Ammonium nitrate
• C. Silver nitrate
• D. Sodium nitrate

Answer 1

The correct option is B

Ammonium nitrate

$\underset{\left(s\right)}{N{H}_{4}N{O}_3}\stackrel{△}{\to }2H_{2}O\uparrow +N_{2}O\uparrow$

$\underset{\left(s\right)}{NaN{O}_3}\stackrel{△}{\to }\underset{\left(s\right)}{NaN{O}_2}+O_2\uparrow$

$\underset{Lunarcaustic}{2AgN{O}_3\left(s\right)}\stackrel{2}{\to }Ag\left(s\right)+2N{O}_2\left(g\right)+O_2\left(g\right)$

$2Pb(N{O}_3{)}_2\to \underset{\left(s\right)}{2PbO}+4N{O}_2\uparrow +O_2\uparrow$
