The following table of heats of dilution can thus be drawn up : 



The quantities within the brackets are extrapolation values. 



The following general conclusions may be drawn from the above facts : 



(l) That, in spite of the varying thermal effects obtained on diluting different 



solutions, these effects may be expressed in a simple manner for the range over which 



the solutions may be considered concentrated ;
