Question

You are given a $10^{- 5}$ M NaCl solution and $10^{- 8}$ M $AgNO_{3}$ solution. They are mixed in 1: 1 volume ratio. $K_{s p}\left(\right.AgCl\left.\right)=10^{- 5}M^{2}$ . Choose the correct statement.

• A. Precipitation will take place
• B. Precipitation will not take place
• C. Cannot be determined
• D. After 1 hour precipitation will take place

Answer 1

Answer: (B)

$AgNO_{3}\rightleftharpoonsAg^{+}+NO_{3}^{-}$
$NaCl\rightleftharpoonsNa^{+}+Cl^{-}$
$\left[\right.Cl^{-}\left]\right.=\frac{1 0^{- 5}}{2}M$
Use square brackett
$\left(\right.Ag^{+}\left.\right)=\frac{1 0^{- 8}}{2}M$
$Q_{i p}=\frac{1 0^{- 5}}{2}\times \frac{1 0^{- 8}}{2} < K_{s p}$
No ppt will take place.
