Question

Assertion: during double displacement reactions precipitates are usually formed.
Reason: precipitation reactions produce insoluble salt.
(A) assertion is true reason is correct explanation
(B) assertion is true reason is not correct explanation

Answer 1

Answer → (A) Assertion is true and reason is the correct explanation ..

==================================================================

Double Displacement Reactions are those reactions that involve an exchange of ions. We may consider the following reaction :

$\implies \: Na_2SO_4 + BaCl_2 \: \rightarrow \: BaSO_4 \: + 2NaCl$

Such reactions are also called precipitation reaction because it generally involve the formation of an insoluble ppt.

Here in this case , a white coloured precipitate of Barium Sulphate is formed!

Answer 2

answer

 (A) Assertion is true and reason is the correct explanation

explanation

==================================================================

Double Displacement Reactions are those reactions that involve an exchange of ions. We may consider the following reaction :

\implies \: Na_2SO_4 + BaCl_2 \: \rightarrow \: BaSO_4 \: + 2NaCl⟹Na2SO4+BaCl2→BaSO4+2NaCl

Such reactions are also called precipitation reaction because it generally involve the formation of an insoluble ppt.

Here in this case , a white coloured precipitate of Barium Sulphate is formed!
