Cobalt And Nickel

The experiments recorded in the following pages were begun nearly five years ago, at a time when opinion was still much divided as to the atomic weight of cobalt and nickel. It seemed to me that it would be a step in advance if it could be settled which of the two is the greater, for while perhaps the majority of chemists represented the atomic weight of cobalt as greater than that of nickel, some still assigned to them both the same value, while Mendeleeff did not hesitate to invert the order by making Co = 58·5 and Ni = 59. After taking into account all the best evidence on the subject, it appears certain that the atomic weight of cobalt is greater than that of nickel, but the fact remains that the values differ from each other by an amount which is less than the difference between any other two well established atomic weights, the respective numbers being variously represented by different authorities as follows :— The object of my experiments, however, soon developed into a wider field, for it appeared that the results obtained with these two metals might be made the means of further testing the validity of the law of Dulong and Petit, inasmuch as temperatures at which the specific heats would he determined are not only very remote, hut about equally remote, from the melting points of these two metals. Both metals are now obtainable in a pure state, and after melting and solidification under the same conditions are presumably in the same state of aggregation. Their atomic weights, though not known exactly, are undoubtedly very near together, as are also the densities of the metals and other of their physical properties.

The densities, refractive indices, and viscosities of liquid n-nonadecane and n-nonadecyl benzene were investigated at temperatures not too far above their respective melting points. Except for the viscosities, no significant differences were observed in the behavior of the two hydrocarbons. The n-nonadecane + n-nonadecyl benzene system exhibits small positive excess volumes and small negative excess viscosities. The excess refractive index is zero in the entire concentration range.
