Silver nitrate is used in laboratory as a reagent for the detection and determination of____________?
Correct answer: C. Halides
- A. Alkali metals
- B. Aldehydes
- C. Halides
- D. Ketones
Explanation
Silver nitrate detects halide ions because Ag+ forms insoluble precipitates with Cl−, Br− and I−, allowing their presence and amount to be determined. The likely distractor is aldehydes, since silver nitrate is used in Tollens' reagent, but that test requires ammoniacal silver nitrate rather than silver nitrate alone.

About Solubility Product
The solubility product constant, Ksp, represents the equilibrium concentrations of ions from a sparingly soluble salt, each raised to its stoichiometric power. Problems involve writing Ksp expressions, calculating molar solubility, applying the common-ion effect and predicting precipitation from the ionic product.
