Bunsen coefficient: definition

Bunsen s Definition—The coefficient k denotes the quantity of C02 m cubic centimeters at 0° C and at the pressure of the experiment absorbed by 1 gram of the liquid... 

The solubilities of gases in liquids may be expressed in various ways. In the definition of the Bunsen coefficient the solubility is expressed as the volume of the ideal gas reduced to O C and 1 atm pressure soluble in a unit volume of liquid under the gas pressure of 1 atm and at the temperature of measurement. The Ostwald solubility ki — Vgl V oiy is defined as the ratio of the volume of absorbed gas to the volume of the absorbing liquid, measured at the same temperature. The Bunsen solubility coefficient a and the Ostwald coefficient L on the assumption of ideal gas behavior are related to the simple g-moles/liter concentration scale c by the relationships which are applicable when P = 1 atm ... 

The Henry coefficient He j depends on both the nature of the absorptive i and the absorbent / (washing agent). The values of the Hemy coefficients significantly increase with rising temperatures. In practice, the Bunsen s absorption coefficients a are very often used. Their definition is...
