1 answer

To identify the reaction between AgNO3 (silver nitrate) and NaCl (sodium chloride) using the Claim, Evidence, Reasoning (CER) format:

Claim: The reaction between AgNO3 and NaCl is a double displacement (or precipitation) reaction.

Evidence:

  1. When AgNO3 and NaCl are mixed, a white precipitate of AgCl (silver chloride) forms, which is an indication of a chemical reaction occurring. The balanced chemical equation for the reaction is: \[ AgNO_3 (aq) + NaCl (aq) \rightarrow AgCl (s) + NaNO_3 (aq) \]
  2. The formation of a solid precipitate is a characteristic sign of a double displacement reaction. In this case, Ag+ ions from AgNO3 combine with Cl- ions from NaCl to form the insoluble AgCl.

Reasoning: In double displacement reactions, the cations and anions of the reactants exchange partners to form new products. Here, the Ag+ ion pairs with Cl- to produce the insoluble AgCl precipitate, while the Na+ ion pairs with the NO3- ion to remain in solution as NaNO3. The formation of a precipitate indicates that a chemical change has occurred, thus confirming the identification of the reaction type.
