Table 247 

 LOWERING OF FREEZING POINTS BY SALTS IN SOLUTION 



267 



In the first column is given the number of gram-molecules (anhydrous) dissolved in iooo grams 

 of water ; the second contains the molecular lowering of the freezing point ; the freezing point 

 is therefore the product of these two columns. After the chemical formula is given the molecular 

 weight, then a reference number.
