Answer:

The solubility of AgCl in 1 m A g N o_{3} is \bold{1.2 \times 10^{-9}}

Explanation:

Given:

The solubility of silver chloride is 1.37 \times 10^{-5} m at the temperature of 298 k.

To find:

The solubility of AgCl in 1m A g N o_{3}

Let us consider the solubility of AgCl is s.  

So solubility of each ion will be:

Step 1:

i. NaCl gives sodium ion and chloride ion.  

ii. Here chloride ion is common so that the solubility of AgCl decreases, because of the presence of the common ion.

Step 2:

i. Molarity of NaCl is 0.1 M.

ii.    The total solubility of chloride ion in AgCl is (0.1+s).  

Step 3:

\mathrm{Ksp}=\left[\mathrm{Ag}^{+}\right]\left[\mathrm{Cl}^{-}\right]

Let us substitute the known values,  

We get,

1.2 \times 10^{-10}=s \times(0.1+s)

When the ksp value is low then the value of s can be neglected.

Therefore,

1.2 \times 10^{-10}=s \times(0.1+s)

Step 4:

To find the value of s

\begin{array}{l}{\mathrm{S}=1.2 \times 10^{-10} / 0.1} \\ {=1.2 \times 10^{-9}}\end{array}
