Module 9

Question 1

Colloids?

Answer 1

They are milky, opaque, cant filter and does not seperate (ex. milk, butter etc)

Question 2

Solutions?

Answer 2

transparent, ant filter, does not seperate, light

Question 3

Solute vs Solvent

Answer 3

solute - the dissolved
solvent the substance it dissolves in

Question 4

“like dissolves like”

Answer 4

similar molecular forces form solutions

ex. i2 and ccl4 bc non polar

Question 5

Henry’s Law states

Answer 5

solubilityt of gas is directionally proportionate to the partial pressure of gas at constant temperature

Question 6

Does pressure have effect on liquids and solids?

Answer 6

no

Question 7

Electrolytes formed

Answer 7

when ions are in the water - charged

Question 8

Solvation is..

Answer 8

when clsuter of solvent molecules surround a dissolved solute molecule or ion

Question 9

What does a saturated solution contain?

Answer 9

It contains the max amount of solute in the solvent at equillibrium

Question 10

What is miscible?

Answer 10

it means that it is mutually soluble in all proportions

Question 11

What are the properties of solutions?

Answer 11

Colligative property - solitions property based on the number of dissolved particles, NOT chemical identity
- vapor pressure is lower for solutions than pure solvents
- Boiling point is higher for a solution than a pure solvent
- Freezing point is lower for a solution than a pure solvent
- Osmosis occurs when it is seperated from a pure solvent by a semi permeable membrane
