Chem 106 Exam 1 || With Latest Answers
Homogeneous Mixtures - Correct Answer Composition may vary; appears to be one substance, but
really contains multiple materials; most are actually solutions
Aqueous Solutions - Correct Answer Have water as solvent, and solid, liquid, or gas as the solute
Solutions - Correct Answer Homogeneous mixtures
Solute - Correct Answer The component of the solution that changes state
Solvent - Correct Answer The component that keeps its state
Entropy - Correct Answer (Delta S): The measure of energy dispersal and disorder in the system
Solvent-Solute Interactions - Correct Answer The interactions between a solvent particle and a solute
particle
Solvent-Solvent Interactions - Correct Answer Interactions between a solvent particle and another
solvent particle
Solute-Solute Interactions - Correct Answer Interactions between a solute particle and another solute
particle
Miscible - Correct Answer Capable of being mixed; capable of mixing in any ration without separation of
2 phases
Soluble - Correct Answer When one substance (solute) dissolves in another (solvent)
, Insoluble - Correct Answer When one substance does not dissolve in another
Exothermic - Correct Answer Gives off energy; typically spontaneous
Endothermic - Correct Answer Absorbs energy; reaction can also be spontaneous
3 Steps for Solution Formation - Correct Answer 1. Separating the solute into its constituent particles
(endo); 2. Separating the solvent particles from each other to make room for the solute particles (endo);
3. Mixing the solute particles with solvent particles (exo)
Hydration - Correct Answer =Ion-Dipole Interactions; when ions dissolve in water
Temperature - Correct Answer For most solids: solubility increases as T increases; Gases: more
predictable as solubility decreases as temp increases
Dynamic Equilibrium - Correct Answer Rates of dissolution and depression become equal
Saturated Solution - Correct Answer Solution in which dissolved solute's in dynamic equilibrium with
solid (or undissolved) solute
Unsaturated Solution - Correct Answer Solution containing <equilibrium amount of solute
Pressure - Correct Answer Gas: Solubility increases as P increases
Dilute Solution - Correct Answer One containing small quantities of solute relative to amount of solvent
Concentrated Solution - Correct Answer One containing large quantities of solute relative to amount of
solvent
Molarity - Correct Answer (M): amount of solute (in moles) divided by volume of solution (in liters)
