_{DON’T FORGET YOUR PENCIL AND CALCULATOR}

Chapter 6     

Equilibrium

Equilibrium constants and reaction quotients

             —forms, values, calculations, and progress toward equilibrium

             —effects of disturbances on a system at equilibrium

             —calcuations (amounts-to-K or K-to-equilibrium amounts—ICE tables)

             —K values and when assumptions can be made

Chapter 7 & 8        

Weak acids and bases

Conjugate acids and bases

pH scale, K_w, K_a and K_b

Acid and base calculations and concepts

             —concentrations and K_{a, b} and pH

             —K values and when assumptions can be made

             —titrations, concentrations, and pH (strong acids & bases as well as weak)

             —buffers, concentrations, and pH

             —reading titration curves (what are predominant species, important equilibria, etc.)

Solubility

             —solubility product constants

             —ion-product expressions (equilibrium equation describing dissolution)

             —calculations (solubility and concentrations of ions—pure solution & common ion effect)

Complex ion formation and calculations

Good luck and try not to stress out!
