Solution concentration (molarity) M = n/V , V always in L
M1V1=M2V2 ( dilution calculations)
Stoichiometry of reactions in solutions M1V1=M2V2 ( dilution calculations)
Ionic reactions (formula unit equation, complete ionic and net ionic equation). Solubility rule
Types of ionic equations: acid-base, precipitation, gas evolution.
Oxidation-reduction reactions (how to distinguish ox-red reactions vs. ionic equations)
Oxidation, reduction, reducing and oxidizing agent.
Dynamic Equilibrium and equilibrium constant, expressing Equilibrium constant for chemical reactions
Large and Small equilibrium constant
Relationship between Kc and Kp
Heterogeneous equilibria and Kc or Kp expressions for heterogeneous reactions.
Problems: Finding equilibrium constant if concentrations are known, finding equilibrium concentrations if constant is known (ICE table), approximation in solution if K is relatively small and initial concentration is relatively large.
Le Châtelier’s Principle: when a chemical system at equilibrium is disturbed, the system shifts in a direction that minimizes the disturbance
Effect of Concentration, Pressure (Volume) and Temperature Change on equilibrium.
Classification of Acids and Bases. Acids: Strong, weak, binary, oxyacids, carboxylic acids. Strength of acids depends on structure. Bases: ionic, covalent. Strength of bases.
