How to determine if a Salt is Acidic, Basic, or Neutral AND find the pH | Tutorial

This is a tutorial mini-lesson video going through the PowerPoint on how to determine if a salt (ionic compound) is acidic, basic, or neutral. This includes parts of the PowerPoint that I give to my AP Chem class. It first recalls the relationship between Ka and Kb for conjugate acid-base pairs (if you need more information about this, go to my video here: • Relationship between K... )
It then uses this to rationalize about the strength of conjugate acid-base pairs (the stronger the acid, the weaker the conjugate base)
It then goes through the logic of thinking back to the acid and base that formed the salt. The conjugate of a weak species will also be weak (so the conjugate of a weak base will be slightly acidic. The conjugate of a weak acid will be slightly basic). Conjugates of strong species will have negligible strength and be neutral.
It then walks you through how to write ionization equations for these weakly acidic or basic ions (also called hydrolysis equations).
The ions from acidic or basic salts represent an equilibrium condition, and thus problems will involve an ICE Box or derivation from an ICE Box. The video shows how to calculate the pH.
If you need more detail about the 5% rule and how to use ICE boxes to solve weak acid problems, go to my video here: Watch this video first, which walks you through how to solve strong and weak acid problems in more detail: • How to Solve Strong an...
