Question

Write chemical equation of double displacement reaction which is also a (a) Precipitation reaction (b) Neutralisation reaction. 3

Answer 1

a) BaCl2+Na2SO4=NaCl2+Ba2SO4

Answer 2

When a certain reaction takes place in which base and acid reacting together that reaction is known as neutralization reaction.

Option - B

To prove the reaction let us see an example:

• When reaction with NaOH happens with HCL it will give sodium chloride and water that is salt and water.
• The reaction takes place when two salts are reacting together such that one is becomes insoluble.

Hence it forms a precipitate an example of such a reaction is given below.

• $AgNO_{3}$ and sodium chloride react together Silver chloride precipitate is formed in a solution of $NaNo_{3}$.
