8

Solute particles are ....

Ions or molecules

9

Solutions don't....... When left standing

Seperate

10

Amount of solute in a given amount of solvent or solution

Concentration

11

Little bit of solute compared to amount of solvent

Dilute

12

Concentration is described in two ways...

Qualitatively
Quantititatively

13

Comparing amounts without being exact

Qualitative concentration

14

Lots of solute compared to amount of solvent

Concentrated

15

It's an exact measurement of the amount of solute and solvent

Quantitative concentration

16

Quantitative concentration is expressed in two ways

Molarity (M)
molality (m)

17

It's the number of moles of a solute per liter of solution

Molarity

18



m = ....

mol
m = ------
L

19

Molality M ==

Moles of solute
---------------

20

its the process of an ionic compound breaking into single ions -

dissociation

36

naming acids ....

look @ ending (ate, ite, ide)

37

it is a special version of a double - displacement reaction

neutralization reaction

38

it is a number on a scale
scale is various colors
it measures acid
