24
Q

what did Arrhenius say

A

1) Acids increases the number of hydrogen ions in a solution
2) bases increases the number of hydroxide ions in a solution

25
What did Brønsted-lowry say
1) Acids donate (H+) and turns into a conjugate base 2) bases accept (H+) and turns into a conjugate acid
26
what did Lewis say
1) acids accepts one electron(-) 2) bases donates an electron(-) 3) they both form a covalent bond
27
True or False - the stronger an acid or base, the weaker the conjugate
True
28
True or False - the weaker an acid or base, the stronger the conjugate
True
29
what type of ions so portion transfers favor
weak ions
30
What are the 4 types of Acids
Monophonic Diprotic Polyprotic Triprotic
31
what does monophonic mean
the element can only donate 1 proton (+) to the molecule
32
what does Diprotic mean
the element can donate 2 protons (H+)
33
what does polyprotic
the element can donate more then 2 or more protons (H+)
34
what does triprotic mean
the element can donate 3 protons (H+)
35
What does it mean for a compound to be amphoteric
they can act either as an acid or base ex. water
36
what is neutralization
the reaction of hydronium (H3O) and Hydroxide (OH) to form water and salt
37
what is the pH of acid rain
~3 or less
38
what does acid rain to to the environment
damages buildings + life
39
What is the self ionization of water
when 2 water molecules produce hydronium (H3O) and hydroxide (OH)
40
what numbers are acids on the pH scale
0-6
41
what numbers are considered to be strong acids
0-3
42
what numbers are considered to be weak acids on the pH scale
4-6
43
what numbers on the pH scale are bases
8-14
44
what numbers on the pH scale are considered to be strong bases
11-14
45
what numbers on the pH scare are considered to be weak bases
8-10
46
what number on the pH scale is neutral
7
47
where do you start counting the SIG FIGs for the pH scale
all numbers after the decimal
48
What is titration
the controlled addition and measurement of a reactions between one known and one unknown concentrations
49
what are the three types of graph points on a titration graph
1)Midpoint 2)Equivalence points 3)end point
50
what is the midpoint
halfway to equivalence
51
what is a buffer
a solutions that resists change in pH ex blood
52
what are the equivalence points
the point where the acid and base were in equal amounts
53
what is the end point
where indicator changes color
