Important Equations from Environmental Chemistry

  1. Chemical Oxygen Demand (COD): $\text{COD} = \frac{\text{Amount of Oxygen required to oxidize organic matter}}{\text{Volume of sample}}$

  2. Biochemical Oxygen Demand (BOD): $\text{BOD} = \frac{\text{Initial Dissolved Oxygen} - \text{Final Dissolved Oxygen}}{\text{Volume of sample}}$

  3. Water Hardness: $\text{Hardness}=\frac{\text{Equivalents of CaCO}_3}{\text{Volume of water sample}}$

  4. Half-life (t½) of a Radioactive Substance: $N_t = N_0 \left( \frac{1}{2} \right)^{\frac{t}{t_{1/2}}}$

  5. Rate of Reaction: $\text{Rate} = \frac{\Delta [\text{Reactant}]}{\Delta t}$

  6. Gibbs Free Energy Change (ΔG): $\Delta G = \Delta H - T \Delta S$

  7. Nernst Equation: $E = E^\circ - \frac{0.0591}{n} \log_{10} \frac{[\text{Reductant}]}{[\text{Oxidant}]}$

  8. Ideal Gas Law: PV=nRT

  9. Henry's Law: $C = k \times P$

  10. Beer-Lambert Law: $A = \varepsilon \cdot l \cdot c$
