Calculate Kw at different temperatures.
Calculate [H⁺] and [OH⁻] from pH or pOH.
Calculate equilibrium constants and concentrations.
Key concepts include:
Important factors:
Key relationships:
Common uses include:
Kw = [H⁺][OH⁻]
pKw = pH + pOH
pH = -log[H⁺]
pOH = -log[OH⁻]
ln(Kw) = A - B/T
Where:
A, B = Constants
T = Temperature (K)
H₂O ⇌ H⁺ + OH⁻
ΔG° = -RT ln(Kw)
Neutral pH = pKw/2
