Chemistry: Acid-Base Solutions

Given acids or bases at the same concentration, demonstrate understanding of acid and base strength by:
- Relating the strength of an acid or base to the extent to which it dissociates in water
- Identifying all of the molecules and ions that are present in a given acid or base solution.
- Comparing the relative concentrations of molecules and ions in weak versus strong acid (or base) solutions.
- Describing the similarities and differences between strong acids and weak acids or strong bases and weak bases.
Demonstrate understanding of solution concentration by:
1. Describing the similarities and differences between concentrated and dilute solutions.
2. Comparing the concentrations of all molecules and ions in concentrated versus dilute solutions of a particular acid or base.
Use both the strength of the acid or base and the concentration of its solution in order to:
- Describe in words and pictures (graphs or molecular drawings) what it means if you have a:
- Concentrated solution of a weak acid (or base)
- or Concentrated solution of a strong acid (or base) or other combinations.
- Investigate different combinations of strength/concentrations that result in same pH values.
Describe how common tools (pH meter, conductivity, pH paper) help identify whether a solution is an acid or base and strong or weak and concentrated or dilute.
