Types of Chemical Reactions

Types of Chemical Reactions. There are 4 common types of chemical reactions and one special type you will soon know by sight and by description. Types of Chemical Reactions - Synthesis. When you bake a cake, you are creating a single product from more than one ingredient. That is synthesis.

Synthesis, characterization of novel Copper(II), Nickel(II) complexes of N-substituted thiosemicarbazides: Evaluation of

Copper(II) and Nickel(II) complexes of N-substituted Thiosemicarbazide ligands derived from condensation of two thiosemicarbazide and a dicarboxylic acid(malonic/ succinic/phthalic acid) have been synthesized and characterized by elemental and thermal analysis, IR, UV-Vis and EPR spectral studies, and magnetic susceptibility studies. Anti-bacterial, Anti-fungal and Anti-cancer activities have also been carried out on these complexes. Most of the complexes have good antibacterial and antifungal activity and some of them show excellent anticancer activity too.

Analytical application of m-chlorophenylazo-bis-acetoxime (m-CPABA) in the spectrophotometric determination of Nickel (I

Analytical application of m-chlorophenylazo-bis-acetoxime (m-CPABA) in the spectrophotometric determination of Nickel (I

m-Chlorophenylazo-bis-acetoxime has been used for spectrophotometric determination of nickel (II) at 376 nm and a pH of 7.0-8.0. Beer‘s law is obeyed in the range of (2.0-16.0) × 10-5 M. The molar absorptivity and Sandell’s sensitivity values are 3,691 L mol-1 cm -1 and 15.90 ng cm-2 respectively. Log β is determined by two different method i.e. Harvey and Manning‘s method and Purohit‘s method and the values of it are 12.93 and 13.23 respectively. Hydroxytriazenes have been used as analytical reagents for a number of transition metals. Similar compounds arylazobis-acetoximes developed by Bamberger and subsequently used by Sogani & Bhattacharaya as spectrophotometric reagents for determination of various transition metals such as cobalt, iron and copper. In the present paper m-chlorophenylazo-bis-acetoxime (m-CPABA) has besen used for spectrophotometric determination of nickel (II).
