Excerpt from Laboratory Work in Applied Chemistry: For Students in Domestic Science Details OF procedure - Place the beaker one-third filled with water on the wire gauze and heat to boiling. While the water in the beaker is being heated, weigh the convex cover to the nearest milligram, first having scrupulously cleaned and dried it. Measure into the graduated flask 100 c.c. Of the water to be examined or such a volume as will leave not less than 10 milligrams of solid residue on evaporation. Place the weighed convex cover on top of the beaker containing the boiling water and carefully add a portion of the measured volume of water. As it evaporates, add more and more, until the whole has been evaporated. Continue the evaporation until the residue on the cover appears perfectly dry. Cool in a desiccator and weigh with the same precision as before. Calculation OF result. - Express the result as parts per million and as grains per U. S. Gallon. Consult works in the library or other sources to secure similar data on other waters and arrange them in the form of a table.
