Question

What is the chemical equation for aqueous sodium chloride and aqueous silver nitrate that react to form solid silver chloride and aqueous sodium nitrate?

Answer 1

Hint: The given statement reveals that the aq. Sodium chloride and aq. Silver nitrate reacts together to form silver chloride (solid) and aq. Sodium nitrate. This is just the double-displacement type reaction with the precipitation of silver chloride.

Complete answer:
Let us study the given reaction statement;
According to the given statement, the balanced chemical equation can be written as;
\[AgN{{O}_{3\left( aq \right)}}+NaC{{l}_{\left( aq \right)}}\to NaN{{O}_{3\left( aq \right)}}+AgC{{l}_{\left( s \right)}}\downarrow \]
The above reaction is mostly used for the illustration of basic solubility rules and solubility equilibria. In general case, all nitrates and halides are soluble individually except for $AgX$ , $Pb{{X}_{2}}$ and $H{{g}_{2}}{{X}_{2}}$ .
Thus, silver halide (here, silver chloride) isn’t soluble and precipitates out as a curdy white solid.

Note:
The precipitates formed from various reactions have different colours as;
Silver chloride – curdy white solid.
Silver bromide – creamy yellow.
Silver iodide – bright yellow.
If the precipitate is kept just still, then the silver halides tend to reduce the silver and thus, the precipitate darkens.
