Career and research

Wilhelm Ostwald is usually credited with inventing the Ostwald process

The Ostwald process is a chemical process for producing nitric acid, which was developed by Wilhelm Ostwald . It is a mainstay of the modern chemical industry. Historically and practically it is closely associated with the Haber process, which provides the requisite raw material,...

Nitric acid , also known as aqua fortis and spirit of nitre, is a highly corrosive and toxic strong acid.Colorless when pure, older samples tend to acquire a yellow cast due to the accumulation of oxides of nitrogen. If the solution contains more than 86% nitric acid, it is referred to as fuming...

 (completed by 1911 or 1913). The date 1908 (six years after the patent) is often given for the invention of the Ostwald process, and it may be that these developments motivated him to do additional work to commercialize the process in that time-frame. Alternatively, six years might simply have been the bureaucratic interval between filing the patent and the time it was granted.

The combination of these two breakthroughs soon led to more economical and larger-scale production of fertilizer

The concept was linked to the ideal gas, according to Ostwald. Ironically, Ostwald's development of the mole concept was directly related to his philosophical opposition to the atomic theory

 this membership ended in 1917 and was not resumed after the war. The 1917 Annual report of the committee ended with the unusual note: "Because of the European war the Committee has had much difficulty in the way of correspondence. The German member, Professor Ostwald, has not been heard from in connection with this report. Possibly the censorship of letters, either in Germany or en route, has led to a miscarriage".

In addition to his work in chemistry, Wilhelm Ostwald was very productive in an extremely broad range of fields. His published work, which includes numerous philosophical writings, contains about forty thousand pages. Ostwald was also engaged in the peace movement of Berta von Suttner.

Among his other interests, Ostwald was a passionate amateur painter who made his own pigments, and who developed a strong interest in color theory
