16
Q

Molarity

A

Mol solute / L solution

17
Q

Mole fraction

A

Mole a/ mole a+ mole b

Unit less

18
Q

Mass %

A

G solvent/ g of solution (100)

19
Q

Molality

A

Mole solute/ kg solvent

20
Q

Volume percentage

A

Parts by volume of solute per 100 parts by volume of solution

21
Q

Parts per million

A

Ppm - parts by mass of solute per million parts by mass of solution

22
Q

Parts per billion

A

Ppb- parts by mass of solute per billion parts by mass of solution

23
Q

Normality

A

N - number of equivalents of solute per liter of solution

24
Q

Rate of solution-= rate of dissolution depends on 3 things…

A
  1. Nature of the solute and solvent- strength of the imf
  2. Temperature - higher temperatures increase the rate with which solute molecules diffuse through the solvent
  3. Surface area- the greater the surface area, the higher the rate of dissolution
25
Q

Saturated solution

A

At equilibrium rate of solution= rate of crystallization

A solution containing the maximum possible amount of dissolved solute at equilibrium

26
Q

Supersaturated solution

A

A solution containing a great than equilibrium amount of solute

27
Q

Henry’s law

A

For solutions of gases in liquids, the solubility of a gas is directly proportional to the partial pressure of the gas above the solution

Solubility = kP
