Strong Acid vs. Weak Acid; Strong Base vs. Weak Base

Postby Lauren Haight 1E » Fri Nov 29, 2019 3:51 pm

What is the difference between a strong acid and a weak acid? That is, what constitutes a strong acid? What is the rule for strong bases?

The main difference between strong acids and weak acids is that strong acids dissociate completely in solution while weak acids do not (the same concept applies for bases). Therefore, strong acids/bases will have higher H+/OH- concentrations in solution (respectively). Because of this, strong acids will have lower pHs than weak acids and strong bases will have higher pHs than weak bases. Bases can also be compared using pOH.
