Answer 1

The common ion effect refers to the decrease in solubility of an ionic compound due to the presence of a common ion. Molar solubility is the mass of a salt that dissolves in 100 mL of water. A saturated solution has dissolved the maximum amount of a compound at a given temperature.

Step-by-step explanation:

a) Common ion effect: A decrease in the solubility of an ionic compound as a result of the addition of a common ion.

b) Molar solubility: The mass of a salt in grams that will dissolve in 100 mL of water.

c) Saturated solution: A solution that has dissolved the maximum amount of a compound at a given temperature. Any further addition of salt will remain undissolved.

d) Solubility product constant: The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation.

e) Solubility: The maximum number of moles of a salt that will dissolve in 1 L of solution.

Answer 2

Answer: a) A decrease in the solubility of an ionic compound as a result of the addition of a common ion : Common ion effect

b) The mass of a salt in grams that will dissolve in 100 mL of water: Solubility

c) A solution that has dissolved the maximum amount of a compound at a given temperature. Any further addition of salt will remain undissolved: Saturated solution

d) The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation : Solubility product constant

e) The maximum number of moles of a salt that will dissolve in 1 L of solution : Molar solubility

Step-by-step explanation:

Solubility is expressed usually as the mass of solute per 100 grams or 100 ml of solvent.

Molar solubility of a solid is expressed as the concentration of the dissolved solid in a saturated solution.

Solubility product constant is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
`K_(sp)`

The common-ion effect is the decrease in solubility of a sparingly soluble salt by the addition to the solution of a soluble compound with an ion in common with the precipitate.

Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent.
