Density of Common Acids
The density of acids varies depending on the specific type of acid and its concentration. Generally, acids are liquid substances with densities ranging from about 1 to 2.5 (g/cm3).
The following table provides a comprehensive list of density values for pure acids at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
