Question

46. In a double displacement reaction, one of the products is insoluble. What type of reaction is that?

Answer 1

• The chemical reaction in which the two reactants (compounds) exchange their respective radicals forming a new compounds is called double decomposition reaction.
• In a double displacement reaction, if one of the products formed is insoluble solid then it is called precipitation reaction. The insoluble solid is called precipitate.

Example: NaCl + AgNO₃ → NaNO₃ + AgCl ⤓

Here AgCl is forming precipitate.
