KEY
Properties of ACIDS AND BASES Practice
1. Name 1 property that acids and bases have in common.
They can conduct electricity, they can change colors of indicators, they react to form water
and salt.
2. Name 2 properties that are not shared by acids and bases (how do they taste different, etc.)
Acids taste sour, they react with metals to produce hydrogen, and they contain H+1 ions
Bases taste bitter, they feel slippery, they all contain (OH)-1 ions
3. What property of lemon juice helps you to identify it as an acid?
The sour taste helps us identify that lemon juice is an acid
4. What gas is given off when magnesium metal is placed in hydrochloric acid?
Hydrogen gas
5. For acids and bases to conduct electricity, what must be found in their solutions?
Ions must be present in order to conduct electricity
6. Given the following compounds, show how they can be ionized:
a. NaOH → Na+1 + (OH)-1
b. LiOH → Li+1 + (OH)-1
c. KOH → K+1 + (OH)-1
d. Are these compounds acids or bases? How do you know?
These are bases because they all contain the (OH)-1 ion called hydroxide
7. Name the compounds.
a. NaOH = Sodium hydroxide
b. LiOH = Lithium hydroxide
c. KOH = Potassium hydroxide
8. Given the following compounds, show how they can be ionized:
a. HCl → H+1 + Cl-1
b. HNO2 → H+1 + (NO2)-1
c. H2SO4 → H+1 + (SO4)-2
d. Are these compounds acids or bases? How do you know?
These are acids because they all contain the (H)+1 ion called hydrogen.
9. Name the compounds.
a. HCl = Hydrochloric acid
b. HNO2 = Nitrous acid
c. H2SO4 = Sulfuric acid
10. Determine if the substance is acidic, basic, or neutral based on the pH value:
a. Lemon juice (pH = 3) Acidic
b. Shampoo (pH = 8) Basic
c. Water (pH = 7) Neutral
d. Coca-Cola (pH = 4) Acidic
