Predicament
•
April 3 marks the passing of Richard Abegg. Abegg was a German chemist who was one of the early researchers of valence theory. His experiments showed a tendency between the maximum and minimum valence levels of elements differed usually by a value of eight. This relationship became known as Abegg’s rule when Gilbert Lewis proposed his octet rule.
Abegg also discovered the principle behind freezing point depression of solvents. The freezing point is at the transition point between the liquid phase and the solid phase of a liquid. It is determined when the vapor pressures of the liquid and solid phases are equal. Abegg found if a solute was added to the solvent, the freezing point would be depressed to a lower temperature.
Abegg was also an avid enthusiast of ballooning. This hobby would ultimately cause his death when he flew his balloon with an engineer and female relative. When the balloon encountered strong winds, they opened the gas valves to cause the balloon to descend. The balloon managed to reach the ground safely and the other two were able to exit the basket. Abegg was caught as a gust of wind as he exited and was crushed by the basket.
