IB DP Chemistry: HL复习笔记10.1.3 Nomenclature
Nomenclature Systematic nomenclature can be used to name organic compounds and therefore make it easier to refer to them The alkanes provide the basis of the naming system and the stem of each name...
IB DP Chemistry: HL复习笔记10.1.2 Understanding Organic Molecules
Representing Formulae Organic compounds can be represented in a number of ways: Empirical Formulae Molecular Formulae Structural Formulae Condensed Structural Formulae The empirical formula shows t...
IB DP Chemistry: HL复习笔记10.1.1 Homologous Series
Homologous Series Organic chemistry is the chemistry of carbon compounds Carbon forms a vast number of compounds because it can form strong covalent bonds with itself This enables it to form long c...
IB DP Chemistry: HL复习笔记9.1.10 Electrolytic Cells
Electrolytic Cells An ionic compound conducts electricity when it is molten or in solution The current causes the ionic compound to split up and form new substances. This process is called electrol...
IB DP Chemistry: HL复习笔记9.1.9 Voltaic Cells
Voltaic Cells Voltaic (or Galvanic) cells generate electricity from spontaneous redox reactions For example: Zn (s) + CuSO4 (aq)→ Cu (s) + ZnSO4 (aq) Instead of electrons being transferred direct...
IB DP Chemistry: HL复习笔记9.1.8 The Winkler Method
The Winkler Method The Winkler Method is a technique used to measure dissolved oxygen in freshwater systems Dissolved oxygen is used as an indicator of the health of a water body, where higher diss...
IB DP Chemistry: HL复习笔记9.1.7 Redox Titrations
Redox Titrations In a titration, the concentration of a solution is determined by titrating with a solution of known concentration. In redox titrations, an oxidizing agent is titrated against a red...
IB DP Chemistry: HL复习笔记9.1.6 The Activity Series
The Activity Series Metals can be ranked in order of reactivity -this is called the reactivity series or just activity series Metals higher in reactivity can displace less reactive metals from thei...
IB DP Chemistry: HL复习笔记9.1.5 Half Equations
Half Equations Oxidation numbers can be used to balance chemical equations Go through these steps to balance a redox equation: Write the unbalanced equation and identify the atoms which change in o...
