HENRY LAW - A HISTORICAL VIEW

Although this brief discussion places Henry's law in a historical context, it was be no means a thorough history. Unfortunately, many important events and personalities have been omitted. However, from this discussion we can see the place of Henry's law in the history of the science of chemistry. Specifically, Henry's law was proposed at the beginning of the era of modern chemistry, which is surprisingly early, and the law remains very popular today. From the first and second laws of thermodynamics and their consequences, Henry's law can be theoretically extended to conditions beyond the reach of Henry's simple apparatus (9).
