He is famous for his Acid-base reaction#Usanovich definition, generalized acid-base theory. Michail Usanovich was born to a Jewish doctor's family in Zhytomyr. After having graduated from Kiev University of Sciences in 1917, he worked in the chemical laboratory of the Academy of Sciences of Ukrainian SSR led by Vladimir Vernadsky up to 1920. He was an employee and the technologist of the Kiev Polytechnical Institute. He became a professor in three universities: Tomsk University in 1930, Central Asian in 1935, and Kazakh in 1944, where he held an academic chair. Main scientific works Mikhail Usanovich developed a number of theories and proved a number of facts, such as: *Quantitative solution theory; *Equations of non-colligative properties of solutions and their depende ...

Law Of Dilution
Wilhelm Ostwald’s dilution law is a relationship proposed in 1888 between the dissociation constant ' and the degree of dissociation ' of a weak electrolyte. The law takes the form :K_d = \cfrac = \frac \cdot c_0 Where the square brackets denote concentration, and is the total concentration of electrolyte. Using \alpha=\Lambda_c/\Lambda_0, where \Lambda_c is the molar conductivity at concentration c and \Lambda_0 is the limiting value of molar conductivity extrapolated to zero concentration or infinite dilution, this results in the following relation: :K_d = \cfrac \cdot c_0 Derivation Consider a binary electrolyte AB which dissociates reversibly into A+ and B− ions. Ostwald noted that the law of mass action can be applied to such systems as dissociating electrolytes. The equilibrium state is represented by the equation: :AB + B^- If ' is the fraction of dissociated electrolyte, then ' is the concentration of each ionic species. must, therefore be the fraction of ' ...

Vladimir Vernadsky
Vladimir Ivanovich Vernadsky (russian: link=no, Влади́мир Ива́нович Верна́дский) or Volodymyr Ivanovych Vernadsky ( uk, Володи́мир Іва́нович Верна́дський; – 6 January 1945) was a Russian, Ukrainian and Soviet mineralogist and geochemist who is considered one of the founders of geochemistry, biogeochemistry, and radiogeology. He was one of the founders and the first president of the Ukrainian Academy of Sciences (now National Academy of Sciences of Ukraine). Vladimir Vernadsky is most noted for his 1926 book ''The Biosphere'' in which he inadvertently worked to popularize Eduard Suess' 1885 term biosphere, by hypothesizing that life is the geological force that shapes the earth. In 1943 he was awarded the Stalin Prize. Vernadsky's portrait is depicted on the Ukrainian ₴1,000 hryvnia banknote. Early life Vernadsky was born in Saint Petersburg, Russian Empire, on in the family of the native Kyiv residents Russi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Empire
The Russian Empire was an empire and the final period of the Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, religious, and economic diversity. From the 10th–17th centuries, the land ...
