Question

When is a chemical reaction categorised as a precipitation reaction?

Answer 1

Answer:

a chemical reaction is a categorised as a precipitation reaction when a precipitation is formed in the products of precipitation is a powder like substance which is insoluble in water a chemical reaction is categorised as precipitation reaction when after a reaction an insoluble solid substance is left behind

✞ A precipitation reaction is a type of chemical reaction in which two soluble salts in aqueous solution combine and one of the products is an insoluble salt called a precipitate.

✞ The insoluble salt that falls out of solution is known as the precipitate, hence the reaction’s name.

✞ Precipitation reactions can help determine the presence of various ions in solution.

⭐precipitation: the process of an insoluble salt forming from its aqueous ions and falling out of solution

⭐net ionic equation: a method or writing a precipitation reaction without spectator ions

$\huge{\fbox{\fbox{\color{lime}{EXAMPLE}}}}$

Aqueous silver nitrate (AgNO3) is added to a solution containing potassium chloride (KCl), and the precipitation of a white solid, silver chloride (AgCl), is observed:

AgNO3 (aq) + KCl (aq) → AgCl (s) + KNO3(aq)

Note that the product silver chloride is the precipitate, and it is designated as a solid. This reaction can be also be written in terms of the individual dissociated ions in the combined solution. This is known as the complete ionic equation:

Ag+ (aq) + NO3−(aq) + K+ (aq) + Cl−(aq) → AgCl (s) + K+ (aq) + NO3−(aq)
