What does lower pKa indicate?

A stronger acid.

What are the Dissociation constants used for?

Ka = a constant that measures the strength of a specific acid.

Kb = a constant that measures the strength of a specific base.

These values stays the same.

Then why have pKa? What’s the difference between this and pH?

pKa:

  • number that shows how easily an acid GIVES UP its hydrogen ion (H+)


pH:

  • How much hydrogen ions is in said solution
