NO CONTENTS SECTION
Describes a method for determining the loss of mass and of non-volatile matter at 250 degree C of anhydrous sodium carbonate for industrial use. Requires an electric oven, capable of reaching a temperature of at least 250 degree C, capable of being regulated so as not to exceed a temperature of 270 degrees C. When analysing sodium carbonate decahydrate avoid loss through sputtering by raising the temperature slowly.
