The solubility of hydrogen in pure liquid iron has been measured as a function of pressure and temperature by the sampling method. Sieverts law is obeyed at all pressure up to one atomosphre. The logarithms of K(=H⁄\sqrtP_H) and the standard free energy of solution of hydrogen in pure liquid iron may be expressed as:

The solubility is reduced by carbon and the effect of carbon on the activity coefficient of hydrogen has been determined as follows:
