208 Table 225. 



LOWERING OF FREEZINC-POINTS BY SALTS 



IN SOLUTION. 



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

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

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

 weight, then a reference number.
