Question

Briefly describe the following chemical reaction (use examples with balanced
equations):
Precipitation reaction

Answer 1

Precipitation reaction is a reaction between two water soluble compounds which results in formation of insoluble compound (also called a precipitate).

For example,

AgNO₃ + KCl -> AgCl + KNO₃

in this example AgCl is insoluble salt precipitated after reaction of two water soluble salts.
