Acids and Bases Flashcards

1
Q

Arrhenius Theory

A

Acid - substance that forms the hydronium ion in water.
Base - substance that forms the hydroxide ion in water.
Pros - Easy to sort a + b
Cons - Many bases don’t contain hydroxides

A

strong = 1
weak = 2

18
Q

A

acidic

19
Q

H+ < OH-

A

basic

20
Q

H+ = OH-

A

neutral

21
Q

pH —> pOH

pOH to OH-

A

10 ^-pOH

23
Q

OH - to pOH

A

-log (OH-)

24
Q

H+ to OH - and vice versa

A

H+ x OH- = 1 x 10^-14

25
Q

H+ to pH

A

-log H+

26
Q

pH to H+

A

10^-pH

27
Q

You must show ___ in a weak acid dissosciation equation

A

Water

28
Q

You must show ___ in a weak acid dissociation equation

A

Water

29
Q

How do conjugate acids/bases differ from their OGs?

A

By one proton

30
Q

Amphiprotic

A

Can donate or accept a proton (act as acid or base)

31
Q

Most common amphiprotic substance

A

water

32
Q

Amphoteric

A

Can react with both acids and bases

33
Q

Polyprotic Acids

A

Can give more than one H+ ion away. H2S, H2CO3

34
Q

What is titration

A

A technique used to determine the unknown molarity of an acid or base. Solution of known molarity is dropped to the other solution until a neutralization rxn takes place

35
Q

Equivalence Point

A

When all of the acid is neutralized by the base - end of titration

36
Q

Indicators

A

show when the equivalence point is used. Most common indicator is phenophaletin.

37
Q

Buffers

A

Solutions that resist changes in pH / keep it constant. Usually weak acid + conjugate base / vice versa.
