Cato Guldberg

Cato Maximilian Guldberg (left) and Peter Waage Cato Maximilian Guldberg (born August 11, 1836 in Oslo, Norway) was a Norwegian chemist and mathematician. Guldberg studied at the Christian University and later became a professor of applied mathematics. Together with his brother-in-law, Peter Waage discovered and published in 1864 the laws of mass action determining the state of chemical equilibrium in relation to the concentrations or pressures of substrates and reaction products (both researchers also studied the equilibrium state of temperature). Their contribution was initially not noticed, probably because their work was published in Norwegian. Also after the publication in 1867 in French the importance of their dependence was not appreciated. The key importance of the law of mass action was noted and publicized by scientists at Oxford, W. Esson and V. Harcourt. The work of Guldberg and Waage over the law of the masses lasted until 1879.

In 1870, Guldberg investigated how the reduction of the coagulation temperature and the vapor pressure of the clean liquid depends on the content of the solute.

In 1880, Guldberg defined the relationship between boiling parameters and the critical temperature of a given liquid. Authoritative control (person):

The poem is also known under the title "Confession of the Polish Child" or "Catechism of a Young Pole". It starts with the words "Who are you? "Little Pole".
