Q

ppb

A

describes a mixture by taking the ratio of solvent to solution and multiplying by a billion

20
Q

electrolyte

A

a solution with dissolved ions that can conduct electricity - has to be soluble, ionic, acid or base

21
Q

colligative

A

a physical property that depends only on the identity of a solute, not the amount

22
Q

malleable

A

a property of metals that allows them to be pounded into shapes

23
Q

ductile

A

a property of metals that allows them to be stretched into wire

24
Q

As IMFs increase, vapor pressure

A

decreases

25
Q

Volatile

A

a liquid with weak imfs that goes to the gas phase (evaporates)readily

26
Q

When IMFs increase, the melting point

A

increases

27
Q

dilute

A

has a relatively small amount of solute present in a solution

28
Q

concentrated

A

has a relatively large amount of solute present in a solution

29
Q

dilution

A

add solvent to a solution to decrease the molarity

30
Q

cohesion

A

forces of attraction that hold neighboring molecules together

31
Q

adhesion

A

forces of attraction that hold molecules onto a surface such as glass

32
Q

intramolecular

A

ionic and covalent bonds

33
Q

intermolecular

A

attraction between neighboring molecules

34
Q

distillation

A

separates mixtures based on differing boiling points

35
Q

Nonpolar

A

classification for hydrocarbons (substances made of only H & C)

36
Q

Mobile

A

when ions are this, they allow electrons to move and thus conduct electricity

37
Q

Overall rule for solubility
