ACID BASE EQUILIBRIA 2 A LEVEL CHEMISTRY NOTES

This is a powerpoint display notes meant for Cambridge, Edexcel and IB chemistry teachers and students.

The se are notes that I use to teach in my class. They ahve been well prepared using the three core books.

The notes include;
Brønsted– Lowry theory of acids and bases

diff erences in behaviour between strong and weak acids and bases and the pH values of their aqueous solutions in terms of the extent of dissociation.

AMPHOTERIC AND AMPHIPROTIC

Conjugate acids and conjugate bases

NITRIC ACID AS A BASE

terms pH, pKa and Kw and use them in calculations

[H+(aq)] and pH values for strong and weak acids and strong bases
choice of suitable indicators for acid–base titrations

changes in pH during acid–base titrations and explain these changes in terms of the strengths of the acids and bases

calculate Ksp from concentrations and vice versa
common ion eff ect
term partition coeff icient
partition coeff icient for a system in which the solute is in the same molecular state in the two solvents.
PH CURVES AND INDICATORS
How a buffer solution works

Making a Buffer solution
How to make a buffer
Calculating the pH of a buffer solution

Uses of Buffers
