- Acids and Alkalis
- Acids
- Substances that produce hydrogen ions, H+(aq), when they are added to water.
- pH values of less than 7
- Hydrogen ions make solutions acidic
- Very strong acids have a pH of between 0-2
- Alkalis
- Bases that dissolve in water to make alkaline solutions.
- Produce hydroxide ions, OH-(aq), in the solution.
- pH values more than 7
- Very strong alkalis have a pH of 12-14
- Water
- Neutral
- pH value of 7
