solutions

Question 1

solution…

Answer 1

homogenous mixture of two or more substances

Question 2

solvent…

Answer 2

doing the dissolving

Question 3

solute…

Answer 3

being dissolved

Question 4

solubility

Answer 4

the maximum amount of solute that dissolves in a given amount of solvent at a specified temperature

Question 5

saturated solution….

Answer 5

maximum amount of solute dissolved in solvent

Question 6

unsaturated solution

Answer 6

has the ability to dissolve more solute

Question 7

factors affecting solubility

Answer 7

1. structure (polarity/molecular shape)
2. pressure (only affects gas)
3. temperature (depends on state of matter)

Question 8

polar substances are more likely to dissolve in…

Answer 8

polar substances

Question 9

Nonpolar substances are more likely to dissolve in…

Answer 9

non polar substances

Question 10

polar solvents that need to be memorized

Answer 10

H2O (water), CH2Cl2 (dichloromethane), CH3OH (methanol), CH3CH2OH (ethanol)

Question 11

Nonpolar solvents that need to be memorized

Answer 11

CCl4 (carbon tetrachloride), C6H14 (Hexane), C7H8 (toluene)

Question 12

pressure effects

Answer 12

• increasing pressure over a solution will increase the solubility on GAS
• pushes gas down
• NO EFFECTS ON LIQUIDS OR SOLIDS

Question 13

Temperature effects (solids and gasses in water)

Answer 13

• for water solubility increases when temp increases

- for gases solubility decreases when temp increases
