Q

How does dissolving occur

A

The solvent attracts individual particles of solute, pulls them apart and surrounds them.

19
Q

What ways increase rate of the reaction

A

Temp change by increasing, agitation, high surface area

20
Q

Dissolution

A

Solute in a solvent forms a solution.

21
Q

What breaks into ions

A

Electrolytes

22
Q

Dilute

A

Make a liquid thinner by adding another solvent to it

23
Q

Concentration

A

Compares the amount of solute in a solution.

24
Q

Concentration and dilute are compared how

A

Qualitatively

25
Q

Molarity

A

Number of moles in solute in one liter of solution

26
Q

Molarity formula

A

Amount of solute(mol)/volume of solution

27
Q

Molality

A

Measure moles solute and kg solvent separately, then mix

28
Q

G~> kg

A

3 decimal places to the right

29
Q

Molality formula

A

Moles solute/kg solvent

30
Q

Hydrate example

A

CuSO4 * 5H2O

Copper 2 sulfate pentahydroxide

31
Q

Hydrate

A

Attracted forces that connect

When crystallized,some ionic substances form crystals that incorporate water molecules

32
Q

What happens when a crystalline hydrate dissolves in water

A

The water of hydration returns to the solvent

33
Q

Hydration

A

solution process with water as the solvent.

34
Q

as hydrated ions diffuse into the solution, other ions are exposed and…

A

Drawn away from the crystal surface by the solvent

35
Q

Immiscible

A

Liquids that are t soluble on each other

Oil & water

36
Q

Miscible

A

Liquids that dissolve freely in one another

37
Q

Pressure and solubility

A

Increase in pressure, increase gas solubilities in liquids.

38
Q

Effervescence

A

Escape of a gas from a liquid in which it’s dissolved

39
Q

Henry’s Law

A

Solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid

40
Q

Henry’s law applies to what

A

Gas liquid solutions at constant temp

41
Q

Enthalpy of solution

A

Absorption and release of energy when solution is made

Solute solute: molecules in solute held together by intermolecular forces

42
Q

Solvated

A

A solute particle surrounded by solvent molecules

43
Q

Enthalpy of a solution part 2

A

Heating decreases the solubility of a gas, so dissolution of gasses is exothermic.
Solute solute interaction has little effect on gas enthalpy
