Equation used for smoothing boiling point elevation data 
over temperature range 80-105°C is: 
2 
6 = a+ bt + ct (20) 
where, 
6 = boiling point elevation, °C 
t = condensate boiling point °C 
a,b,c = constants of fit, given in Table 16

Discussion 
The sulfuric acid added to the sea water for removal 
of bicarbonate ions changes the salinity by 1 part in 3000. 
This does not change the BPE in the range of accuracies 
used in this work. 
Boiling point elevation depends on the activity of 
water in the solution. As the concentration of solution
