solubility/diffusion

Question 1

soluble

Answer 1

can dissolve

Question 2

insoluble

Answer 2

cannot dissolve

Question 3

solute

Answer 3

substance that is dissolving

Question 4

solute

Answer 4

substance that dissolves the solvent

Question 5

solution

Answer 5

solute + solvent (mixture)

Question 6

saturates

Answer 6

the max. solute that can dissolve in the solvent

Question 7

solubility

Answer 7

the mass of solute that dissolves in 100cm3

Question 8

suspension

Answer 8

insoluble solid mixed in a liquid

Question 9

dissociate

Answer 9

particles separate, no longer touching

Question 10

aqueous

Answer 10

dissolved in water (aq)

Question 11

how does temp. affect solubility in solids

Answer 11

the solubility increases because more energy to break the bonds

Question 12

how does temp. affect the solubility in gases

Answer 12

the solubility decreases because particles move further apart

Question 13

diffusion

Answer 13

the random movement of particles that causes them to spread and mix, the net movement is from high conc. to low conc.

Question 14

factors affecting diffusion

Answer 14

temp.
in gases because particles move faster
size or mass of particles- larger particles need more energy so move slower.

Question 15

how can the rate of diffusion be shown

Answer 15

using a precipitation reaction

Question 16

solubility rules

Answer 16

all nitrates are soluble
all gp 1 compounds are soluble
all halides are soluble except with ag or Pb 2+
all sulfates are soluble except with Ca, Sr, Ba, Pb, Ra
all hydroxides, oxides, and carbonates are insoluble
