Raman spectroscopy of basic copper(II) and some complex copper(II) sulfate minerals: Implications for hydrogen bonding
Studies of the basic Cu sulfate minerals have existed for some time (Fowles 1926; Richmond and Wolfe 1940; Ungemach 1924). Such minerals are formed under specific conditions of pH and sulfate ion concentration. The minerals in this group are dolerophanite Cu2OSO4 (Richmond and Wolfe 1940), antlerite Cu3SO4(OH)4 (Araki 1961; Finney and Araki 1963), brochantite Cu4SO4(OH)6 (Helliwell and Smith 19...
متن کاملMicrowave synthesis, basic spectral and biological evaluation of some copper (II) mesoporphyrinic complexes.
Cu(II) complexes with asymmetrical and symmetrical porphyrinic ligands were synthesized with superior yields using microwave irradiation. The paper presents the synthesis of 5-(3-hydroxyphenyl)-10,15,20-tris-(4-carboxymethylphenyl)-21,23-Cu(II)-porphine in comparison to its symmetrical complex 5,10,15,20-meso-tetrakis-(4-carboxy-methylphenyl)-21,23-Cu(II) porphine. The two compounds were charac...
متن کاملSome Basic Probability
In the previous section of the notes, we noted that a random experiment was defined by a procedure and an observation, and that the sample set was the set of all possible observations. For the purposes of computing probabilities, it is often convenient to define the observations in such a way that the outcomes can be assumed to be equally probable.1 The advantage of a sample space with equiprob...
متن کاملDietary effects of zinc, copper and manganese chelates and sulphates on dairy cows
The experiment was carried out on 90 dairy cows in the period from 6 weeks before calving up to 305th day of lactation. The animals randomly divided into 3 groups were fed with diets containing different chemical forms of zinc, manganese and copper applied in mineral mixtures. The control group received these trace elements as sulphates, but in experimental groups 20 or 30% of daily needs were ...
متن کاملOn the Dissociation of Silver, Thallium and Zinc Sulphates in Some Molten Nitrates
The present paper aims at inquiring the ionization of some sulphates when dissolved in molten nitrates having suitable characteristics, and of which heats of fusion and cryoscopic constants were already well k n o w n T h e solutions of A g 2 S 0 4 in L i N 0 3 and K N 0 3 , of T1 2 S0 4 in L i N 0 3 , N a N 0 3 , and A g N 0 3 and of Z n S 0 4 in L i N 0 3 , N a N 0 3 , K N 0 3 , and A g N 0 3...
