Table 21 5. 21/ 



LOWERING OF FREEZING-POINTS BY SALTS IN SOLUTION. 



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

 grammes of water; the second contains the molecular lowering of the freezing-point ; the freez- 

 ing-point is therefore the product of these two columns. After the chemical formula is given 

 the molecular weight, then a reference number.
