Front (Question)

• a physicochemical property that refers to the ability of a given “solute” to be “dissolved” in a given amount of “solvent”

Back (Answer)

Solubility

Front (Question)

property of solute to dissolve in a solvent

Back (Answer)

Solubility

Front (Question)

a substance dissolved to create a solution

Back (Answer)

solute

Front (Question)

dissolving medium

Back (Answer)

solvent

Front (Question)

a solution that contains “less amount of solute” than the solvent

Back (Answer)

unsaturated solution

Front (Question)

liquid mixture composed of the solute uniformly dissolved in the solvent

Back (Answer)

solution

Front (Question)

the process of dissolvin

Back (Answer)

dissolution

Front (Question)

a solution that contains “more amount of solute” than the solvent

Back (Answer)

supersaturated solution

Front (Question)

a solution with the “maximum amount of solute” dissolved in the given solvent

Back (Answer)

saturated solution

#10

Front (Question)

certain substances exhibit “solubility property” wherein they “mix in all proportions”, forming a homogenous mixture, this property is termed as

Back (Answer)

miscibility

#11

Front (Question)

predicting solubility is important:

Back (Answer)

• in “purifying or isolating” a compound • when “extracting a molecule” from its natural source • when “designing a pharmaceutical product” which needs to be soluble enough to elicit its desired effect • when performing “synthesis reactions” especially in the formulation of organic drugs • the “partitioning of drug molecules” within the body between the blood and various tissues are governed by the solubility concept

#12

Front (Question)

predicting solubility is important:

Back (Answer)

• “purifying or isolating” • “extracting a molecule” • “designing a pharmaceutical product” • “synthesis reactions” • “partitioning of drug molecules”

#13

Front (Question)

the solubility is controlled by the energy balance of intermolecular forces of attraction between which molecules?

Back (Answer)

• solute-solute • solute-solvent • solvent-solvent

#14

Front (Question)

IFA means

Back (Answer)

intermolecular forces of attraction

#15

Front (Question)

pertains to the polarity of compounds

Back (Answer)

the rule of “like dissolves like”

#16

Front (Question)

Van der Waals dispersion forces

Back (Answer)

non-polar molecules

#17

Front (Question)

polar molecules

Back (Answer)

dipole-dipole interaction (or hydrogen bonding under certain circumstances)

#18

Front (Question)

dipole-dipole interaction (or hydrogen bonding under certain circumstances)

Back (Answer)

polar molecules

#19

Front (Question)

non-polar molecules

Back (Answer)

Van der Waals dispersion forces

#20

Front (Question)

depends on the “polarities of the individual bonds” and the “shape of the molecule”

Back (Answer)

Polarity ! * evaluating these factors are quite complicated because of the “complexities of the molecules”themselves

#21

Front (Question)

All hydrocarbons are _____________

Back (Answer)

non-polar

#22

Front (Question)

Compounds with electronegative element (O and N) are generally ___________, but the degree of polarity varies from slightly polar to highly polar.

Back (Answer)

polar

#23

Front (Question)

The presence of __________ does not alter the polarity of the compound; therefore, these compounds are only slightly polar

Back (Answer)

halogen

#24

Front (Question)

Adding more “carbon” to the chain makes the compound more ___________

Back (Answer)

non-polar
