Grundkonzepte
| Name | Formel | Einheit |
|---|---|---|
| Stoffmenge | mol | |
| Molare Masse | g/mol | |
| Avogadro-Konstante | /mol | |
| Stoffmengenkonzentration | Gilt für: V is the volume of the solution, not of the solvent; units mol/L So fragt die echte Prüfung | mol/L |
| Molares Volumen (STP) | Gilt für: Gases only; the molar volume is 22.4 L/mol at STP (0 °C, 101 kPa) — that value does not carry over to other conditions So fragt die echte Prüfung | L/mol |
| Massenanteil | Gilt für: The denominator is the mass of the solution (solute plus solvent), not of the solvent So fragt die echte Prüfung | % |
| Dichte | g/mL | |
| Ideales Gasgesetz | - | |
| Verdünnungsformel | Gilt für: The amount of solute is unchanged by dilution; valid only when diluting, not reacting So fragt die echte Prüfung | - |
Stöchiometrie
| Name | Formel | Einheit |
|---|---|---|
| Massenerhaltung | - | |
| Gasdichte (STP) | g/L | |
| Mittlere molare Masse | g/mol | |
| Theoretische Ausbeute | % |
Thermochemie
| Name | Formel | Einheit |
|---|---|---|
| Enthalpieänderung | kJ/mol | |
| Satz von Hess | kJ/mol | |
| Verbrennungswärme | kJ | |
| Neutralisationswärme | kJ/mol | |
| Bindungsenergie und Enthalpie | kJ/mol |
Chemisches Gleichgewicht
| Name | Formel | Einheit |
|---|---|---|
| Gleichgewichtskonstante (Kc) | - | |
| Druckgleichgewichtskonstante (Kp) | - | |
| Reaktionsquotient | - | |
| Umsatzrate | % |
Chemische Kinetik
| Name | Formel | Einheit |
|---|---|---|
| Reaktionsgeschwindigkeit | Gilt für: An average rate over the interval, always positive; rates quoted for different species are in the ratio of their stoichiometric coefficients So fragt die echte Prüfung | mol/(L*s) |
| Geschwindigkeitsgesetz | - | |
| Arrhenius-Gleichung | - | |
| Halbwertszeit (1. Ordnung) | s |
Elektrochemie
| Name | Formel | Einheit |
|---|---|---|

| Nernst-Gleichung | V |
Säure-Base-Gleichgewicht
| Name | Formel | Einheit |
|---|---|---|
| pH-Definition | - | |
| pOH-Definition | - | |
| Ionenprodukt des Wassers | Gilt für: The ionic product is 1×10⁻¹⁴ at 25 °C; it varies with temperature only — adding acid or base does not change it So fragt die echte Prüfung | - |
| pH + pOH | - | |
| Säuredissoziation | - | |
| Puffergleichung | - |
Löslichkeitsgleichgewicht
| Name | Formel | Einheit |
|---|---|---|
| Löslichkeitsprodukt | - | |
