Acids and Bases

Question 1

POlyprotic Acids

Answer 1

Contain more than 1 H

Increasing H atom= easier to dissociate= Increase acid strength

Rule only applies to polyprotic acids

(H2SO4 stronger than SHO4-, but not stronger than HCl)

Question 2

H2SO4

Answer 2

Only strong polyprotic acid

Question 3

Strong Acids

Answer 3

HCl
HBr
HI
HNO3
HClO4
H2SO4

Question 4

Strong Bases

Answer 4

LiOH
KOH
Ca(OH)2
Mg(OH)2

Question 5

Trends- Increasing acicity=

Answer 5

Increase KA=
Decrease pKa=
Decrease pH

Question 6

Trends- Increasing alkalinity=

Answer 6

Increase Kb=
Decrease pKb=
Increase pH

Question 7

BL Acids

Answer 7

H+ donor

Needs H

Question 8

BL Base

Answer 8

H acceptor

Needs lone pair

Question 9

Conjugate Acid

Answer 9

Base+ H

Strong base= weak CA

Question 10

Conjugate Base

Answer 10

Acid after losing H

Strong acid= weak CB

Question 11

Arrhenius acid/bases

Answer 11

Same as BL, but are H+ donors/acceptors in aquesous solution

Question 12

Lewis Acids

Answer 12

Electron pair acceptors

Contain valence orbitals

Question 13

Lewis Base

Answer 13

Electron pair donors

Contain lone pair

Question 14

Strong Acid+ Strong Base=

Answer 14

Neutral salt

Question 15

Strong Acid + Weak Base

Answer 15

Acidic salt

Question 16

Weak Acid + Strong Base

Answer 16

Basic salt

Question 17

Weak Acid + Weak Base

Answer 17

Reaction does not go to completion

Question 18

Amphoteric Salts

Answer 18

Have both acidic and basic properties

Can behave as either acids or bases

i.e. (Al(OH)4

Question 19

Buffers

Answer 19

Solution that resists pH change

Acidic components reacts with OH when strong base is added

Basic component reacts with H+ when strong acid is added

Question 20

Buffer Can Be Formed By

Answer 20

WA + BB

SA + WB

SB + WA
