ten examples of precipitation reaction
Answers
Answer:
Salts containing silver, lead, and mercury (I) are insoluble. Carbonates (CO2−3), phosphates (PO3−4), sulfides, oxides, and hydroxides (OH−) are insoluble. Sulfides formed with group 2 cations and hydroxides formed with calcium, strontium, and barium are exceptions. Other words is this is Precipitation Reaction.

✞ 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
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)
