Solubility - AP Chemistry

A saturated solution contains the maximum concentration of solute that can dissolve at a given temperature. This represents equilibrium between dissolved and undissolved solute.

Adding a soluble salt can increase ionic strength, potentially increasing solubility. The salt effect can enhance solubility through ionic interactions.

Nitrates are generally soluble without exceptions. All nitrate compounds dissolve readily in water.

Gas solubility decreases with increasing temperature. Higher kinetic energy reduces gas-liquid interactions.

Gas solubility decreases with increasing temperature. Higher kinetic energy reduces gas-liquid interactions.

A precipitation reaction is when two solutions combine to form an insoluble solid. This occurs when the reaction quotient exceeds $K_{sp}$.

Chlorides are generally soluble except for $AgCl$, $PbCl_2$, and $Hg_2Cl_2$. These three chlorides are notable exceptions to solubility.

$NaCl$ is soluble in water. Sodium chloride follows the alkali metal solubility rule.

Sulfides are generally insoluble except for those of alkali metals and $NH_4^+$. Only alkali metals and ammonium form soluble sulfides.

A solution is a homogeneous mixture of two or more substances. Solutions have uniform composition throughout.

Molarity $M = 0.25 \text{ mol/L}$. Using $M = \frac{n}{V} = \frac{0.5}{2}$.

Smaller particles dissolve faster, increasing the rate but not the solubility. Surface area affects dissolution rate, not total solubility.

$K_{sp} = [Ca^{2+}][F^-]^2$. The stoichiometry shows 1:2 ion ratio in the expression.

Stirring increases the rate of solute dissolving, but not the solubility. Stirring affects dissolution rate, not equilibrium solubility.

Hydroxides are generally insoluble except for alkali metals and $Ba(OH)_2$. These are the only hydroxides with significant solubility.

Henry's Law states that the solubility of a gas is directly proportional to its partial pressure. This describes the pressure-solubility relationship for gases.

Solubility of most solids increases with increasing temperature. Higher temperature provides energy to break intermolecular forces.

A dilute solution contains a small amount of solute relative to the solvent. This describes low solute concentration relative to capacity.

Both temperature and pressure affect solubility. Both factors influence how much solute dissolves.

Solubility is the maximum amount of solute that can dissolve in a solvent at a given temperature. This defines the equilibrium limit of dissolution.

A solute is a substance dissolved in another substance, forming a solution. The solute is the dissolved component of a solution.

Solubility can increase with increasing ionic strength due to the salt effect. More ions in solution can affect solubility equilibria.

Gas solubility in liquids increases with increasing pressure. Higher pressure forces more gas molecules into solution.

$K_{sp}$ is the product of the concentrations of the ions each raised to the power of its coefficient. This equilibrium expression applies to saturated solutions.

Solubility $S = \sqrt[3]{\frac{K_{sp}}{4}}$. For $AB_2$: $K_{sp} = [A^{2+}][B^-]^2 = 4S^3$.
