Acid/Base Help Files (ALL on Exam 2 for Spring 2012!!!)

Here are some helpful PDF files about ACID/BASE Theory. Everything is catagorized as Type 1 or 2 and the type of species put into solution.

Don't forget the BASICS, know your Strong Acids and Bases

Here's a nice help sheet on the pH and pOH Scales

General Acid/Base Theory - compare the equations used for all acid/base equilibria. (Exam 3 and 4)

Type 1 problems - only ONE species goes into the solution

Weak Acid - only a weak acid (HA) put into solution.

Weak Bases - only a weakbase (B) put into solution.

Salt of a Weak Base - only a salt of a weak base (BHX) put into solution.

Salt of a Weak Acid - only a salt of a weak acid (NaA) put into solution.

Fraction of Species - although there are many "scary" equations given on this helpsheet, you don't have to really know any of them. You DO need to be able to interpret a fraction of species diagram though. They are extremely useful when dealing with multiple pH's of a given solution which is EXACTLY what is going on with buffers and titration curves.



Type 2 problems - TWO species go into the solution

Weak Acid and its Salt - both a weak acid (HA) and the salt of that weak acid (NaA) put into solution.
NOTE: a typo on on this help sheet was CORRECTED on 2/26/12. The old version had an ICE table with all negatives for x. It now is correct in showing +'s on the right side.

Weak Base and its Salt- both a weak base (B) and the salt of that weak base (BHX) put into solution.

Here are two help sheets on Titration Curves

Here are some Excel Spreadsheets on Titration Curves
