“Ostwald was a great protagonist and an inspiring teacher. He had the gift of saying the right thing in the right way. When we consider the development of chemistry as a whole, Ostwald's name like Abou ben Adhem's leads all the rest ... Ostwald was absolutely the right man in the right place. He was loved and followed by more people than any chemist of our time.” PeopleMenWayWholeInspirationScienceNamesTeacherDevelopmentRight ThingOur TimeChemistryRight WayRight PlaceProtagonistsChemistRight Man Author:Wilder Dwight Bancroft
“There is one experiment which I always like to try, because it proves something whichever way it goes. A solution of iodine in water is shaken with bone-black, filtered and tested with starch paste. If the colorless solution does not turn the starch blue, the experiment shows how completely charcoal extracts iodine from aqueous solution. If the starch turns blue, the experiment shows that the solution, though apparently colorless, still contains iodine which can be detected by means of a sensitive starch test.” IfsWayTryingMeanDoeStillsShowsScienceTurnsBlackWaterProveSolutionsTestsBlueBonesExperimentsSensitiveTestedCharcoalColorlessIodine Book:Applied Colloid Chemistry, General Theory Source: Applied Colloid Chemistry, General Theory
