Boiling Point of Common Acids
The boiling point of acids varies depending on their specific chemical composition. Acids are diverse compounds, and their boiling points are influenced by factors such as molecular size, intermolecular forces, and the presence of hydrogen bonding.
The following table provides a comprehensive list of boiling point values for common acids under 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
