Mineral replacement reactions in solid solution-aqueous solution systems: Volume changes, reactions paths and end-points using the example of model salt systems

“…In a third scenario, an equilibrium end-point is also reached if the initial crystal has been reacted in part or completely and the compositionally homogeneous replacement is in equilibrium with the solution (upper reaction path in fig. 6), a situation which is analogous to Berthelot-Nernst precipitation (Berthelot, 1872;Nernst, 1891). The composition of this solid solution-aqueous solution pair depends on the initial solution to solid ratio and the initial compositions of solution and solid.…”

Salicylate Method for Ammonia Quantification in Nitrogen Electroreduction Experiments: The Correction of Iron III Interference

“…[1][2][3] In this context, nitrogen fixation as ammonia is viewed as a key process, [4][5][6][7] since ammonia synthesis is considered as one of the foundational chemical processes of the human society, [8][9][10] supporting approximately 27% of the world's population over the past century. 11,12 Since French historian and chemist, Marcellin Pierre Eugène Berthelot, observed in 1859 the formation of a blue-colored dye when ammonia, phenol and hypochlorite were mixed, 13,14 a great number of studies have investigated this reaction, which is known nowadays as the Berthelot or indophenol reaction. 15 This term has since been generalized to refer to any reaction in which a phenolic compound reacts with ammonia and a hypochlorite source to form an indophenol-like dye, where the family of dyes is characterized by the indophenol group.…”
