Bunsen solubility coefficient

The Bunsen absorption coefficient, also Bunsen coefficient or Bunsen absorption coefficient (symbol: or) is a named after the chemist Robert Wilhelm Bunsen dimensionless parameter of physical chemistry. It indicates what proportion by volume of a gas at a matching with the standard pressure partial pressure in the physical standard state absorbed by another substance. Of special importance is the Bunsen coefficient in determining the gas dissolving capacity of liquids depending on the operating pressure, for example, for fluids in hydraulic systems.

In the standard condition applies:

In case of different from normal pressure after the partial pressure Dalton's law applies:

With

• - Volume of the dissolved gas
• - Volume of the solution
• - Atmospheric pressure ( normal pressure )
• - Absolute pressure ( from the standard pressure deviating partial pressure)
