Question

Write a balanced chemical equation for precipitation reaction

Answer 1

Answer:

Explanation:

2KI     +    (CH3COO)2Pb    =     2(CH3COO)K       +    PbI2

Lead iodide is precipitate

Answer 2

Solution:

• The chemical reaction in which a solid residue is produced at the end of reaction is known as Precipitation reaction.

• The solid residue which is produced is called Precipitate.
• Example of precipitation reaction:

        $AgNO_3_{(aq)} + NaCl_{(aq)} \rightarrow AgCl (s) \downarrow + NaNO_3_{(aq)}$
