Chapter 14: Acid-Base Equilibria

Question 1

arrhenius acid and base

Answer 1

-acid = dissociates to yield H3O+
-base= dissociates to yield OH-

Question 2

bronsted lowry acid and base

Answer 2

-acid = proton donor
-base = proton acceptor

Question 3

strong bases

Answer 3

-M2O or MOH, M= Group 1A metals
-MO or M(OH)2, M= Group 2A
-EXCEPT Mg

Question 4

the rxn will favor…

Answer 4

the formation of the weaker acid and base

Question 5

strength of acid/base and it conjugate is…

Answer 5

inversely related

Question 6

[H3O+] > [OH-]

Answer 6

acidic

Question 7

[H3O+] < [OH-]

Answer 7

basic

Question 8

pH > 7

Answer 8

basic

Question 9

pH < 7

Answer 9

acidic

Question 10

basic solution

Answer 10

-high pH
-high [OH-]

Question 11

acidic solution

Answer 11

-high pOH
-high [H3O+]

Question 12

relationship between Ka and pKa

Answer 12

pKa = -logKa
-low pKa = high Ka
-low pKa = stronger acid

Question 13

percent dissociated

Answer 13

([H+]/[HA]) x 100

Question 14

cation of weak base and anion of strong acid

Answer 14

acidic salt

Question 15

metal cation and anion of strong acid

Answer 15

acidic salt

Question 16

anion of weak acid and cation of strong base

Answer 16

basic salt

Question 17

anion of weak acid often function as

Answer 17

weak bases

Question 18

cation of weak base and anion of weak acid

Answer 18

compare K values

Question 19

EN increases

Answer 19

acidity increases

Question 20

bond strength decreases

Answer 20

acidity increases

Question 21

if proton is bonded directly to a halogen, look at…

Answer 21

bond strength (length of bond)

Question 22

oxoacids with the same # of O atoms

Answer 22

compare EN (as EN increases, acidity increases)

Question 23

oxoacids with different # of O atoms

Answer 23

strength of acid increases with # of O atoms

Question 24

acidic oxides

Answer 24

non-metal

Question 25

basic oxides

Answer 25

metal (ionic)

Question 26

lewis base

Answer 26

-donates electron pair
-bronsted-lowry bases are also lewis bases

Question 27

lewis acids

Answer 27

-accepts electron pair
-many that are not bronsted lowry acids are lewis acids
