Question 5

Strong Acids do what in water?
Examples?

Answer 5

completely ionize (break apart into ions) when dissolved in water

HCl, HBr, HI, HNO3, HClO4, H2SO4

Examples?

Answer 9

Completely ionize (break apart into ions) when dissolved in water
LiOH, NaOH, KOH, Sr(OH)2, Ca(OH)2, Ba(OH)2

Question 10

Weak Bases do what in water?

Answer 10

partially ionize when dissolved in water

Question 11

Water is amphoteric, what does this mean?

Answer 11

can act as either an acid or a base

Question 12

Water Constant (KW)

Answer 12

measure of the self ionization of water

Question 13

pH =

Answer 13

-log [H3O+]

Question 14

the H scale is logarithmic which means that a change of 1 actually scales to a change by a factor of

Answer 14

10

Question 15

Acid/Base reactions exist in some form of

Answer 15

equilibrium

Question 16

Acid strength is actually relative and depends on:

what is this known as?

Answer 16

the ability of the group to give up a proton.

the acid-dissociation constant (KA)
The larger the KA = the easier it is to remove the proton (more acidic)
Can use pKA instead (lower values = more acidic)
