The reaction AgNO₃ + NaCl → AgCl↓ + NaNO₃ is best classified as a:
A{'text': 'Double-displacement reaction'}
B{'text': 'Combination reaction'}
C{'text': 'Simple displacement reaction'}
D{'text': 'Photochemical reaction'}
Answer & Solution
Correct answer: A. {'text': 'Double-displacement reaction'}
1. Two ionic compounds exchange their partners during this reaction.
2. The exchange pattern AB + CD → AD + CB is called a **double-displacement reaction**.
3. The insoluble silver chloride forms a white precipitate.
4. A single displacement involves only one element; combination forms one product.
