A common concentration is 49% (48-52%) but there are also stronger solutions (e.g. 70%) and pure HF has a boiling point near room temperature.
- 7.4: Standard Enthalpy of Formation - Chemistry LibreTextsThe standard enthalpy of formation is a measure of the energy released or consumed when one mole of a substance is created under standard conditions from its pure elements. The symbol of the standard enthalpy of formation is ΔH f. Δ = A change in enthalpy. o = A degree signifies that it's a standard enthalpy change.
