what is precipitation reaction???
Answers
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.

Step-by-step explanation:
How to identify
Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
Predict
Predicting Precipitation Reactions
Sometimes ions in solution react with each other to form a new substance that is insoluble (does not dissolve), called a precipitate.
A set of rules can be used to predict whether salts will precipitate.
The property of certain ions to precipitate can be used to isolate a particular ion from the solution.
How to do
If there is a precipitation reaction, write the complete and net ionic equation that describes the reaction.
Solution:
Step 1: Determine the possible products using the general double displacement equation.
Step 2: Predict whether either of the possible products is water insoluble.
Step 3: Write the complete equation.
