AR226-2236 Henry's Law Constant for C-8 in Water Henry's Law fo r a component in water is a useful approximation of the partial pressure of that component above a specified composition in aqueous solution, in its most general form, the equation that defines Henry's Law is where /j = Pure component fugacity of component 1 Hx = Henry's Law Constant for component 1 x t = Liquid phase mole fraction of component 1 Henry's Law is fundamentally valid only as x1 -> 0 and fo r ideal solutions, but is commonly used as an approximation tool at low concentrations.
