KH 6.1 - 6.2 (Solubility and Concentration)

An unsaturated solution is

• a solution that has the "perfect" amount of solute dissolved

• a solution that doesn't have enough solute dissolved

• a solution that has been tricked to dissolve more solute than it should be able to

A supersaturated solution is

• a solution that has the "perfect" amount of solute dissolved

• a solution that does not have enough solute dissolved

• a solution that has been "tricked" to have more solute dissolved than it should have

A saturated solution is

• a solution that has the "perfect" amount of solute dissolved

• a solution that does not have the right amount of solute dissolved

• a solution that has been "tricked" into dissolving more solute than it should have

An electrolyte is

• an ionic compound

The following is the correct dissociation of KNO₃

• KNO₃ --> K⁺¹ + N^-3 + 3O^-2

• KNO₃ --> K + NO₃

• KNO₃ --> K⁺¹ + 3NO^-1

• KNO₃ --> K⁺¹ + NO₃^-1

The dissociation of Al₂(SO₄)₃ is

• Al₂(SO₄)₃ --> Al + SO₄

• Al₂(SO₄)₃ --> 2Al + 3SO₄

• Al₂(SO₄)₃ --> 2Al⁺³ + 3SO₄^-2

• Al₂(SO₄)₃ --> 2Al⁺³ + 3S^-2 + 12O₄^-2
