Dimensionless Henry’s Law Constant

03/29/26

“How can we quantify whether a substance is likely to stay in water or escape as water?”

Some substances escape from water solutions quickly, like volatile organic compounds, while others stay contentedly in water. We can find this out by taking the ratio of the concentration in vapor to the concentration in water, represented by the Dimensionless Henry’s Law Constant. The dimensionless Henry’s Law constant is equal to the regular Henry’s Law Coefficient divided by the universal gas constant and the temperature.
