Question

The solubility product of $AgCl$ is $1.8 \times 10^{-10}$. Precipitation of $AgCl$ will occur by mixing which of the following solutions are mixed in equal volumes?

• A. $10^{-8}\, M\, Ag^+$ and $10^{-8}\, M \,Cl^-$ ions
• B. $10^{-3}\, M\, Ag^+$ and $10^{-3}\, M \,Cl^-$ ions
• C. $10^{-6}\, M\, Ag^+$ and $10^{-6}\, M \,Cl^-$ ions
• D. $10^{-10}\, M\, Ag^+$ and $10^{-10}\, M \,Cl^-$ ions

Answer 1

Answer: (B)

For precipitation, ionic product $>$ solubility product In all other options, ionic product is less than solubility product.
