Titrimetric methods of analysis

The combination of potentiometric methods with multivariate calibration techniques allows complex mixtures to be analyzed. In this study, a new method was developed and reported for simultaneous determination of copper(II) and zinc(II) cations in a mixture by titrimetric methods. The developed method permits simultaneous cation analysis with low detection limits, just by using a pH electrode. This work has achieved the challenging goal of developing a cost-effective and applicable method that can be applied in most laboratories due to independence of any chemical instruments.

The prototypical catalytic reductiveC–Cbond formations, the Fischer-Tropsch reaction [1] and alkene hydroformylation [2], were discovered in 1922 and 1938, respectively [3,4]. These processes, which involve reductive coupling to carbon monoxide, have long been applied to the industrial manufacture of commodity chemicals [5]. Notably, alkene hydroformylation, also known as the oxo-synthesis, has emerged as the largest volume application of homogeneous metal catalysis, accounting for the production of over 7 million metric tons of aldehyde annually.

Colloid and surface chemistry occupy a paradoxical position among the topics of physical chemistry. These are areas which have traditionally been considered part of physical chemistry and are currently enjoying more widespread application than ever due to their relevance to environmental and biological problems. At the same time, however, colloid and surface chemistry have virtually disappeared from physical chemistry courses. These topics are largely absent from the contemporary general chemistry course as well.

As currently taught, the introductory course in analytical chemistry emphasizes quantitative (and sometimes qualitative) methods of analysis coupled with a heavy dose of equilibrium chemistry. Analytical chemistry, however, is more than equilib- rium chemistry and a collection of analytical methods; it is an approach to solving chemical problems. Although discussing different methods is important, that dis- cussion should not come at the expense of other equally important topics.

Titrimetric Methods of Analysis Titrimetry, trong đó chúng ta đo khối lượng của một thuốc thử phản ứng stoichiometrically với các chất phân tích, lần đầu tiên xuất hiện như là một phương pháp phân tích trong những năm đầu thế kỷ thứ mười tám. Không giống như gravimetry, titrimetry ban đầu đã không nhận được chấp nhận rộng rãi như là một kỹ thuật phân tích. Nhiều người nổi tiếng cuối thế kỷ thứ mười chín nhà hóa học phân tích ưa thích gravimetry theo titrimetry và vài trong số các văn bản tiêu chuẩn từ thời kỳ bao...
