Acid Based Solutions

This simulation allows students to:

• Demonstrate an understanding of acid and base strength, given acids or bases at the same concentration, by:

1. Relating the strength of an acid or base to the extent to which it dissociates in water
2. Identifying all of the molecules and ions that are present in a given acid or base solution.
3. Comparing the relative concentrations of molecules and ions in weak versus strong acid (or base) solutions.
4. 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.

• Investigate different combinations of strength and 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.
