What is the color of precipitates of AgCl?
Correct answer: D. White
- A. Yellow
- B. Green
- C. Blue
- D. White
Explanation
Silver chloride forms a white curdy precipitate because Ag+ combines with Cl− to produce insoluble AgCl. The likely mistake is choosing yellow, the colour of AgI, while confusing the different precipitates of silver halides.

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.
