Equilibrium › Chemical EquilibriumEquilibrium › Ionic Equilibrium: Acids, Bases and pHEquilibrium › Buffers, Salt Hydrolysis and Solubility ProductChapter 6Contains Standard contentEquilibrium
In a sealed bottle of soda the gas never stops moving between the liquid and the space above, yet nothing seems to change. Many reactions stop short in the same way, with forward and backward reactions running at the same rate. In this chapter you write equilibrium constants, predict how an equilibrium shifts, and then turn to ions in water: acids and bases, pH, buffers and the solubility of salts. Python solves the equilibrium equations for you.

The Equilibrium Constant
Dynamic equilibrium in physical and chemical changes, the law of mass action, Kc and Kp and how they are linked, the reaction quotient, finding equilibrium amounts, and Le Chatelier's principle.
Acids, Bases and pH
Arrhenius, Bronsted-Lowry and Lewis acids and bases, conjugate pairs, the ionisation of water, the pH scale, and the ionisation constants of weak acids and bases.
