 nitromethane; and 7, orthonitrophenol. Examining the figure for the 

 typical salts, it will be observed that in the case of silver iodide, am- 

 monium chloride, potassium nitrate, and ammonium nitrate the curves

in dilute solution approach a straight line. In the case of ammonium 

 bromide and potassium iodide the number of points is not sufficient to 

 actually determine the form of the curve in dilute solutions. In the case 

 of other salts, the figures of which are not shown here, similar results 

 were obtained; that is, in those cases where sufficient data are available 

 at low concentrations, the points approximate a straight line and this
