Answer : Precipitation occurs when the product of the ion concentrations exceeds the $K__{sp}$ .

Explanation :

Ionic product : It is the product of the concentrations of the ions in solution raised to the same power by its stoichiometric coefficient in a solution of a salt. This takes place at any concentration. The ionic product is represented as, Q.

Solubility product constant : It is defined as the product of the concentration of the ions present in a solution raised to the power by its stoichiometric coefficient in a solution of a salt. This takes place at equilibrium only. The solubility product constant is represented as, $K__{sp}$ .

There are three cases for the solubility :

When $Q$ this means that the solution is unsaturated solution and more solid will be dissolve.
When $Q=k_{sp}$ this means that the solution is saturated solution.
When $Q>k_{sp}$ this means that the solution is supersaturated solution and solid will be precipitate.

Hence, the precipitation occurs when the product of the ion concentrations exceeds the $K__{sp}$ .

The concentration of gallium in silicon is 5.0 × 10−7 at%. What is the concentration in kilograms of gallium per cubic meter?

Step2247 [10]

Answer:

[ Ga ] = 1.163 E-8 Kg/m³

Explanation:

%wt = [(mass Ga)/(mass Si)]*100 = 5.0 E-7 %

⇒ 5.0 E-9 = m Ga/m Si

assuming: m Si = 100 g = 0.1 Kg

⇒ m Ga = (5.0 E-9)*(0.1 Kg) = 5 E-10 Kg

∴ density (δ) Si = 2.33 Kg/m³

⇒ Volume Si = (0.1 Kg)*(m³/2.33 Kg) = 0.043 m³

⇒ [ Ga ] = (5 E-10 Kg)/(0.043 m³) = 1.163 E-8 Kg/m³

⇒ [ Ga ] =
