Examples of Precipitation Reactions

• Both the silver nitrate(AgNO₃) and sodium chloride(NaCl) are colorless solutions and when reacts together they form a white precipitate ( AgCl ) and a colorless solution.

AgNO₃ (aqueous) + NaCl(aqueous) → AgCl ↓ + NaNO₃ (aqueous)

• Both the aqueous lead nitrate react with aqueous potassium iodide to give solid lead iodide precipitate and aqueous potassium nitrate.

Pb(NO₃)₂ (aqueous) + 2KI (aqueous) → Pbl₂ ↓ +2KNO₃ (aqueous)

• Both the Sodium carbonate and calcium chloride are mixed to form a CaCO₃ precipitate and aqueous NaCl

CaCl₂ (aqueous) + NaCO₃ (aqueous) → CaCO₃ ↓ + 2NaCl (aqueous)

Precipitation Reaction in Real Life

In our daily life we see many chemical reactions takes place, Some examples we see daily in our life are burning, corrosion, cooking of food and digestion etc. In all these chemical reactions precipitate is formed. As you can see by combining two different soluble salts in an aqueous state, two different products were formed. One formed product is insoluble in the solution and is thus precipitated out. which known as the precipitate is formed.

There are many examples of Precipitation Reaction which we use in our daily life:

• We use Precipitation Reaction in Water pipes, water pipes consists of Hard water which has many impurities. Generally Magnesium and calcium oxides are mainly found in water pipes as precipitates.
• Precipitation can be used to separate the cation or anion, a soluble salt. These reactions are used to remove salt from the water and to segregate items.
• Precipitation reactions even occurs in the human body between antibodies and antigens.
• Precipitation reactions even occurs in the human body ,the reaction takes place between calcium ions and oxalic acid that are present in food results in calcium oxalate, which is a type of kidney stones.

Precipitation Reaction is a chemical reaction in which dissolved substances react to form one or more solid products. Precipitation reactions help in identifying the presence of different ions present in a particular solution. In Precipitation Reaction, the ions of two different aqueous solutions react with each other to form an insoluble solid. This solid substance is called a precipitate and it settles at the bottom of the container. Precipitation acts as a major component in the water cycle and is responsible for depositing fresh water on the planet. Precipitation Reactions can be represented in chemical equations, which play an important role in various chemical processes. Students first read about Precipitation Reactions in Class 10.

In this article, we will learn about the Precipitation Reaction as well as the applications, Precipitation Reaction in Real Life, chemical reactions and also provide a step-by-step guide to help you easily understand Precipitation Reaction. So, let’s start with the definition of Precipitation Reaction.
