* Formation of a precipitate: When these two solutions are mixed, a white solid called silver chloride (AgCl) forms and precipitates out of the solution. This precipitate is insoluble in water.
* New chemical bonds: The reaction involves the breaking of existing bonds in NaCl and AgNO₃ and the formation of new bonds in AgCl and NaNO₃.
* Irreversible reaction: This reaction is essentially irreversible under normal conditions. You can't easily get back the original reactants from the products.
The reaction equation:
NaCl (aq) + AgNO₃ (aq) → AgCl (s) + NaNO₃ (aq)
Key takeaway: The formation of a new substance (silver chloride) with different chemical properties than the reactants indicates a chemical change.
