Determining the Molarity of Acetic Acid in Vinegar Abstract
Chemistry
This experiment aimed to determine the molarity of acetic acid in vinegar. The process involved titrating the acetic acid with a strong base, sodium hydroxide, to identify the equivalence point of this chemical reaction. Phenolphthalein was used as an indicator because it changes color on the basic side of the pH scale. To ensure accuracy,…
Applications with Nuclear Chemistry with Medicine
Chemistry
Medicine
Nuclear chemistry has a significant impact on the medical field, especially in relation to radiation. Various techniques are employed to introduce radiation into the human body, including X-ray imaging and radiation therapy. These aspects are prominently highlighted in nuclear medicine. Nuclear chemistry in nuclear medicine uses radioactive isotopes as biological tracers and for dilution purposes….
Lab Report on Solubility
Chemistry
Nature
Water
The analyses of the mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques, we examined our solutions such as SiO2 (sand), NH4Cl (ammonium coloride), and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions, we made…

Chargaff Erwin’s Contributions in Biochemistry
Chemistry
Erwin Chargaff, born 1905 in Czernowiz, Austria, was a pioneer in biochemistrycontributing to the understanding of DNA. He, in 1928, earned his doctoral degree inchemistry at the University of Vienna’s Spath’s Institute in 1928. Erwin began his careerin biochemistry at Yale University, working under Rudolph J. Anderson from 1928 to1930. His early work included stories…
