4
Sugar, corn syrup, modified corn starch, citric acid, tartaric acid, natural and artificial flavors, yellow 5, yellow 6, red 40, blue 1 What ingredients make these… so sour?
5
Base – a compound that produces ions when dissolved in Examples: Milk of Magnesia – neutralizes stomach acid Drain cleaner–

7
Use the same rules as for ions (name the cation, then name the anion) NaOH Ca(OH) 2 KOH
8
An acid must contain a and ionize in water to produce An base must contain a and dissociates in water to produce
9
Classify each of the following as an Arrhenius acid (A – acid) or base (A – base). Ca(OH) 2 HBr H 2 SO 4 LiOH
10
A Bronsted – Lowry is any substance that can a
11
Neutral[H + ]=[OH - ] Acidic[H + ]>[OH - ] Basic[H + ]<[OH - ]
12
pH is < 7Solution is acidic pH is = 7Solution is neutral pH is > 7Solution is basic
14
[H + ] are often small, so the pH scale is easier to use to represent acidity and basicity. pH range is from to
15
If [H 3 O + ] = 1.0 x 10 –5 M, what is the pH? Is the solution basic, neutral, or acidic?
16
If [H + ] = 0.00089M, what is the pH? Is the solution basic, neutral, or acidic?
17
Given that a solution has a pH of 3.97, determine the [H + ].
18
Similar to pH, there is also pOH. Because [H + ] x [OH - ] =
19
If [OH - ] = 6 x 10 –12 M, what is the pOH? What is the pH? Is the solution basic, neutral, or acidic?
20
What is the pH and the pOH for 5.5 x 10 –7 M HF? pH pOH
21
Given that a solution has a pH of 9.0, determine the [OH - ] and the pOH. pOH [OH - ]
