The common-ion effect primarily describes an increase in the solubility of an ionic precipitate when a soluble compound sharing an ion is added.

Le Chatelier's principle explains the common-ion effect by stating that equilibrium shifts to counteract a disturbance, such as the addition of a common ion.

The common-ion effect causes an increase in the concentration of dissolved ions of a sparingly soluble salt.

The common-ion effect is exclusively observed with salts and does not apply to weak electrolytes.

Adding a common ion to a solution of a sparingly soluble salt will generally lead to increased precipitation of that salt.

The common-ion effect applies to the solubility of both salts and strong electrolytes.

What happens to the concentration of both ions of a sparingly soluble salt when an additional amount of one of its common ions is introduced into a solution?

Hydrogen sulfide (H₂S) is a strong electrolyte that completely ionizes in aqueous solutions.

The equilibrium reaction for hydrogen sulfide ionization shows it reversibly dissociating into H⁺ and HS⁻.

The acid dissociation constant (K_a) for H₂S is expressed as K_a = [H₂S] / ([H⁺][HS⁻]).

Hydrochloric acid (HCl) is a strong electrolyte that ionizes almost completely in solution.

When HCl is added to an H₂S solution, chloride ions (Cl⁻) act as the common ion.

The addition of H⁺ ions from HCl shifts the H₂S dissociation equilibrium to the right, increasing HS⁻ concentration.

A buffer solution is characterized by containing a strong acid and its conjugate base.

Adding a conjugate ion to a buffer solution will always decrease its pH.

Sodium acetate (NaCH₃CO₂) is a weak electrolyte that partially dissociates in solution.

Acetic acid (CH₃CO₂H) is a strong acid that ionizes completely in solution.

When sodium acetate and acetic acid are together, acetate ions from sodium acetate suppress the ionization of acetic acid.

In an acetate buffer, the common-ion effect decreases the percent dissociation of acetic acid and increases the solution's pH.

The hydronium concentration in a solution containing both acetic acid and sodium acetate is higher than in a solution containing only acetic acid.

When HCl is added to an H₂S solution, the concentration of un-ionized H₂S molecules decreases.

The common-ion effect always applies to all ionic compounds, including transition-metal compounds.

Copper(I) chloride (CuCl) dissolves when chloride ions are added because it forms soluble complex ions like CuCl₂⁻.

The uncommon-ion effect is also known as the salt effect or the diverse-ion effect.

The uncommon-ion effect, unlike the common-ion effect, causes a decrease in the solubility of a salt.

The primary mechanism for the uncommon-ion effect is the reduction of inter-ion attraction, making ions more likely to precipitate.

The formation of complex ions can sometimes lead to the dissolution of an insoluble compound even when a common ion is added.

The uncommon-ion effect is sometimes referred to as 'salting out.'

The uncommon-ion effect increases solubility because inter-ion attractions make the ions of the sparingly soluble salt less available for precipitation.
