When a base dissolves in water, molecules break apart to form _____
Hydroxide ions (HO-)
Bases increase the concentration of ______ when dissolved in water
Hydroxide ions (OH-)
Acids have a ______ taste.
Sour
Acids have a pH ______
Below 7

Hydrogen gas
Name uses of acids
Areas of Industry and homes, including:
- Keeps swimming pools free of algae
- Stomach acids
- Orange juice and lemon juice
- Vinegar
Acids (can, cannot) conduct electric current when dissolved in water. Why or why not?
Can; hydronium ions are formed when an acid dissolves in water. They can move freely past each other and conduct electric current.
Most acids are ______, meaning they destroy, clothing, body tissue, etc.
Corrosive
Bases have a ______ taste
Bitter
Bases have a ______ feel
Slippery
Bases have a pH ______
Above 7
Bases change ______ Litmus paper ______
Red
Blue
Solutions of bases (can, cannot) conduct electric current. Why?
Solutions of bases increase the number of hydroxide ions in a solution. They can move freely past one another and conduct electric current.
