Define Precipitation Reaction​

Answer 1

$\huge\tt\underline\pink{answer}$

•A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. 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.

Answer 2

$\Large{\underbrace{\underline{\bf{ANSWER\:}}}}:$

➠ A precipitation reaction is a kind of chemical reaction in which two soluble salts in a fluid solution mixes and one of the items is an insoluble salt called a precipitate.

➠ The precipitate stays in the solution as a barrier or it can also be removed from the liquid by using the process of centrifugation, decantation or filtration. Most of the other salts are insoluble except calcium, barium etc.

➠ Precipitation reactions are generally single replacement reaction or double replacement reactions.

➠ In a double substitution reaction, both ionic reactants separate in water.

➠ For a double replacement reaction to be a precipitation reaction, one of the items must be insoluble in the liquid solution. 

⠀⠀⠀⠀⠀ ⠀✯ Example ✯

☛ Silver nitrate and potassium chloride is a precipitation reaction because solid silver chloride is formed as a product of the reaction.
