The correct option is C double displacement reaction
Reaction of Silver nitrate with Sodium chloride
When aqueous solution of Silver nitrate (AgNO3) is added to a solution of Sodium chloride (NaCl), a white solid precipitate of Silver chloride (AgCl) is formed. Sodium nitrate (NaNO3) is also formed from sodium ions and nitrate ions left in the solution.
The balanced chemical equation for the reaction is:
(Silver (Sodium (Silver (Sodium
nitrate) chloride) chloride) nitrate)
Since a solid precipitate is formed from two aqueous solutions, this reaction is an example of precipitation reaction.
(A) In displacement reactions, an element displaces another element from its salt solution. Therefore, only one displacement takes place during the reaction. Here, both the metals are displaced from its solution, and therefore, it is not a displacement reaction. Option (A) is incorrect.
(B) In synthesis reaction, two or more reactants combine to form a larger product. Here, there are more than one products. Therefore, option (B) is incorrect.
(C) Double displacement reactions involve the exchange of anions between metals. In this reaction, the nitrate ion and chloride ion is exchanged between the two metals. Precipitation reaction occurs by double displacement. Therefore, option (C) is correct.
(D) In analysis reactions, a single reactant decomposes to form more than one product. In the given reaction, two reactants react to form two products. Therefore, option (D) is incorrect.
Therefore, the correct option is (C) double displacement reaction.
