Silver chloride ( $A g C I$ $AgCI$ ) is relatively insoluble in water. At 25 C, $1.3 x 10^{3}$ $1.3 x 10^3$ L of water is needed to dissolve 2.5 g of $A g C l$ $AgCl$ . What mass (in milligrams) of $A g C l$ $AgCl$ will dissolve in 1.0 L of water?

Approx. $2 \cdot m g$ $2*mg$

Explanation:

$Solubility$ $"Solubility"$ $=$ $=$ $\frac{Moles of solute}{Volume of solution}$ $"Moles of solute"/"Volume of solution"$ .

For silver chloride we are given that: $2.5 \cdot g$ $2.5*g$ wil dissolve in over $1$ $1$ $m^{3}$ $m^3$ of water.

And thus, $Solubility$ $"Solubility"$ $=$ $=$ $\frac{2.5 \cdot g}{143.32 \cdot g \cdot m o l^{- 1}} \times \frac{1}{1.3 \times 10^{3} \cdot L}$ $(2.5*g)/(143.32*g*mol^-1)xx1/(1.3xx10^3*L)$ $=$ $=$ $1.34 \times 10^{- 5} \cdot m o l \cdot L^{- 1}$ $1.34xx10^-5*mol*L^-1$ .

And thus silver chloride solute in 1L of saturated water $=$ $=$ $1.34 \times 10^{- 5} \cdot m o l \cdot L^{- 1} \times 143.32 \cdot g \cdot m o l^{- 1} \times 1 L$ $1.34xx10^-5*mol*L^-1xx143.32*g*mol^-1xx1L$ $≅$ $~=$ $2 \cdot m g$ $2*mg$

Typically, you are quoted a $K_{sp}$ $K_"sp"$ for these insoluble salts. $K_{sp} A g C l = 1.77 \times 10^{- 10}$ $K_"sp "AgCl=1.77xx10^-10$ . $K_{sp}$ $K_"sp"$ values can be shown to depend on the molar solubilities.
