Question

What is the change observed when $AgCl$ reacts with $N{H}_3$?

• A. White ppt is formed
• B. Solution become colourless
• C. Yellow ppt is formed
• D. No change is observed

Answer 1

Answer: (B)

when $AgCl$ reacts with $N{H}_3$
$\underset{\text{colour less}}{A{g}^{+}(aq)}+C{l}^{-}(aq)\to \underset{\text{white ppt}}{AgCl(s)}$
$\underset{\text{white ppt}}{AgCl(s)}+2N{H}_3(aq)\to \underset{\text{colour less}}{\left[Ag{\left(N{H}_3\right)}_2\right]}Cl(aq)$
