Waar gebruik je mierenzuur voor?
Mierenzuur kent verschillende toepassingen. Zo wordt de stof gebruikt bij de productie van insuline, in verzachtende en anti-jeuk bodyproducten en in behandelingen bij reuma voor het verlichten van de ontsteking en gewrichtspijn. Mierenzuur kan ook worden gebruikt als conserveermiddel of zuurteregelaar.
Hoe varroamijt bestrijden?
De varroa in het volk kan bestreden worden door het druppelen van oxaalzuur in een suikeroplossing. Dit heeft het grootste effect wanneer dit in broedloze volken gebeurt. Deze behandeling wordt veel toegepast in de winter of bij zwermen zonder broed.
What is Liebig-denigès method?
Liebig–Denigès (L-D) (Liebig [ 8 ], Denigès [ 9 ]) method of determination of cyanide. In the very slowly before the end point, making the titration tedious. In the L-D method, the tempo-
What are the advantages of L-D method over Liebig method?
An advantage of the L-D method compared with the Liebig method is the rapidity of analyses. In the L-D method, slowly. However, the discussion of the mathematical relations in volved with this process was unsatisfactory. The necessity to obtain the functional relationship, as in other approaches,
Can the modified Liebig–denigès (L-D) method be used for cyanide titration?
The paper compares two approaches to the simulated argentometric titration of cyanide with the use of the modified Liebig–Denigès (L-D) method, carried out according to GATES and applied with (1) classical and (2) pH-static titrations. Both approaches are discussed thoroughly and the results obtained from calculations are presented graphically.
What did Liebig do for chemistry?
Liebig was one of the first chemists to organize a laboratory in its present form, engaging with students in empirical research on a large scale through a combination of research and teaching. His methods of organic analysis enabled him to direct the analytical work of many graduate students.
