TABLE 126.— LOWERING OF FREEZING POINTS BY SALTS IN SOLUTION 



In the first column is given the number of gram-molecules (anhydrous) dissolved in 1000 

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

 point depression is the product of these two columns. After the chemical formula is 

 given the molecular weight. Temperatures in °C.
