Hint :First we have to know that a double-replacement reaction exchanges the cations (or the anions) of two ionic compounds. Double replacement reactions are also called metathesis reactions. Precipitation reactions and neutralization reactions are two common types of double replacement reactions.
Complete Step By Step Answer:
A precipitation reaction is a reaction when two aqueous ionic compounds form a new ionic compound that is not soluble in water and you can identify a precipitation reaction using solubility rules. For example (real life), the reaction between lead (II) nitrate and potassium iodide. Both compounds are white solids that can be dissolved in water to make clear, colourless solutions. When you combine the two clear solutions, you get the following reaction:
.
Neutralization reaction is a reaction between an acid and a base producing water and salt. Precipitation is not mandatory for all double displacement reactions. For example,
.
Some other examples of Double Replacement Chemical Reactions are:
When iron(II) sulfide reacts with hydrochloric acid it gives the products, iron chloride and hydrogen sulfide.
i.e., .
When baking soda ( ) reacts with vinegar ( ) to form sodium acetate ( ). The bubbles you see when you mix baking soda with vinegar are the found on the product side of the equation.
i.e., .
Note :
The insoluble product compound is called the precipitate. The solvent and soluble components of the reaction are called the supernatant or supernate respectively. Solubility rules are used to predict whether a precipitation reaction will take place. Displacement reactions can also be a redox reaction, as it often includes simultaneous oxidation and reduction.
