Well, to be honest, in this semester I haven't liked the subjects very much, but if I had to choose one I think it would be chemical laboratory techniques, in part this subject make us closer to the career, we learnt to use the basic instruments that are necessary to work in a laboratory, we learnt doing things because the theorical part was minimal, we began learning the security measures and the instalations of a laboratory, then we learnt how to use the balances, how to prepare solutions and do valuations of them, how to do extractions and distillations, among other things. I haven’t had very good marks in the tests but I think that I learnt a lot of things and that it was a useful subject. I hope the next semester the subjects are more interesting, I will have biology which is my favorite subject since ever and is the subject where I have more knowledge, it was my mention in the university selection test so I think it will be easier for me, so things will be a little bit better...

Well, today I’m gonna write about a known pharmaceutical chemist, Karl Friedrich Mohr, a German pharmacist. He was born in 1806, in Coblenza, Germany, he was the son of a pharmacist what may explain his interest in this field. At the age of twenty one he began his studies of pharmacy in the Heidelberg University, finishing them in the Berlin University. When his father died he inherited his father’s pharmacy. He’s considered the father of volumetric analysis, due to his research needs, he did create and improve some laboratory instruments, he improved the burette which improvement was a clamp called Mohr’s clip, which helped to restrict the flow of gasses and liquids through the simple burette, and actually it is used in flexible tubes. He also helped in the creation of the hydrostatic balance named Mohr-Westphal, used in the laboratory to determinate the densities of liquids. , there’s even a salt that has his name in honor for his advances in chemical assessments. Besides this inv...
