Unit 6 Quiz

Question 1

Diffusion

Answer 1

movement of molecules from a region of high concentration to a region of lower concentration (can happen through air, solvents, etc)

Question 2

solvent-

Answer 2

liquid

Question 3

solute-

Answer 3

solid particle

Question 4

solution-

Answer 4

solvent + solute

Question 5

water is considered the universal

Answer 5

solvent

but not all things can dissolve in it

Question 6

osmosis

Answer 6

diffusion of water.

Movement of H2O (water) from a high concentration of H2O to a lower concentration of H2O

Question 7

Factors that effect the rate of diffusion

Answer 7

1. temperature- (the warmer it is, the faster something will diffuse)
2. size of molecule- (smaller the molecule, the quicker it will diffuse)

Question 8

Tonicity

Answer 8

comparing solute concentration of one solution to the solute concentration of another solution

Question 9

isotonic

Answer 9

equal

Question 10

hypertonic

Answer 10

more solute

Question 11

hypotonic

Answer 11

less solute

2. ions (charged particles)

Question 20

Selective Permeability testing

Answer 20

glucose
starch
protein
chloride
sulfate

Question 21

Glucose

Answer 21

Reagent= Benedict’s

Have to use a third factor (heat) then you get

positive outcome= burnt orange

Answer 23

Reagent= Biuret

Positive Outcome= Purple

Question 24

Chloride

Answer 24

Reagent= Silver Nitrate

Positive Outcome= Milky White

Question 25

Sulfate

Answer 25

Reagent= Barium Chloride

Positive Outcome= precipitate (cloudy looking with stuff in it?)
