플루오린화수소산과 수산화나트륨
HF + NaOH → NaF + H2O
개요
Hydrofluoric acid, despite being a weak acid (Ka = 6.8 × 10⁻⁴), reacts completely with sodium hydroxide to form sodium fluoride and water. HF is unusually dangerous among weak acids because it penetrates skin and causes deep tissue burns by binding calcium ions in bones. The high heat of neutralization reflects the strong H-F bond.
