Question 7

hydration

Answer 7

to surround ions with water molecules

Question 8

dissociation

Answer 8

separation of ionic solid into its own individual ions in a solution

Question 9

miscimble

Answer 9

liquids that mix in all proportions

Question 10

immiscimble

Answer 10

liquids that cannot mix together

Question 11

surfactant

Answer 11

compound that lowers the surface tension of water, therefore allowing polar and non polar solutions mix

Question 12

hydrophobic tail

Answer 12

attracted to grease/oil

Question 13

hydrophilic tail

Answer 13

attracted to water

Question 14

five factors that effect solubility

Answer 14

TAPPT
(Temperature, Agitation, Particle Size, Pressure, Type of solvent)

Question 15

For solids, what happens to the temperature when it increases

Answer 15

particles move around rapidly

Question 16

For gases, what happens to the temperature when it increases

Answer 16

solubility goes down

Question 17

what happens if you stir more

Answer 17

it dissolves better

Question 18

particle size goes down then what

Answer 18

increases solubility bc the surface area increases

Question 19

stock solution

Answer 19

standard solution that needs to be diluted

Question 20

standard solution

Answer 20

regular lab used solution completely pure

Question 21

monoprotic acid

Answer 21

an acid that only ionizes to release one hydrogen ion. This is most acids

Question 22

diprotic acid

Answer 22

an acid that will only ionize 2 hydrogen ions

Question 23

triprotic acid acid

Answer 23

releases 3 hydrogen ions when ionize

Question 24

What is the difference between a strong acid and a weak acid

Answer 24

strong acid completely breaks apart when dissolved in H2O
a weak acid partially breaks apart when dissolved in H20

Question 25

What is the difference between a strong base and a weak base

Answer 25

a strong base completely dissociates into ions when dissolved into H20 A weak base partially dissociates into ions when dissolved into H2O

Question 26

what does pH stand for

Answer 26

power of hydrogen

Question 27

evquivilance point vs end point?

Answer 27

equivalence point: theoretical point where the reactants are completely neutralized endpoint: the observed point where an indicator changes colour, signaling the completion of the titration.

Question 28

what does a base do in water to produce hydroxide ions

Answer 28

dissociates

Question 29

what does an acid do in water to produce hydrogen ions

Answer 29

ionize

Question 30

what is arrhenuis theory of acids and bases

Answer 30

a base dissociates in water to produce hydroxide ions an acid that ionizes in water to produce hydrogen ions.

Question 31

what is the bronsted-lowry theory of acids and bases

Answer 31

a base is a substance that accepts hydrogen ions an acid is a substance that donates hydrogen ions
