Question

State one appropriate observation.

Excess Chlorine gas reacted with Ammonia gas.

Answer 1

• When excess Chlorine gas reacts with Ammonia gas, a yellow-coloured liquid formation is observed.
• And the formed yellow-colored liquid is highly explosive in nature.
• The reaction that is happening here can be represented using a chemical equation as,
  $$\begin{gathered} {\mathrm{NH}}_3\left(\mathrm{g}\right)+3{\mathrm{Cl}}_2\left(\mathrm{g}\right)\to {\mathrm{NCl}}_3\left(\mathrm{l}\right)+3\mathrm{HCl}\left(\mathrm{g}\right) \\ \mathrm{Ammonia}\mathrm{Chlorine}\mathrm{Nitrogen}\mathrm{Hydrogen} \\ \mathrm{gas}\mathrm{gas}\mathrm{trichloride}\mathrm{chloride} \end{gathered}$$
• Here, Ammonia reacts with Chlorine to form Nitrogen trichloride and Hydrogen chloride.
• Therefore, excess Chlorine gas react with Ammonia gas, a yellow coloured liquid formation of Nitrogen trichloride is observed.
