Sodium carbonate revisited.
We present the structure of anhydrous sodium carbonate at room temperature (phase gamma) and 110 K (phase delta) based on single-crystal X-ray diffraction data. The incommensurate phase gamma was determined almost 30 years ago in the harmonic approximation using one modulation wave and first-order satellites. In our work we use satellites up to fifth order and additional harmonic waves to model...
متن کاملGermicidal Efficiency of Sodium Hydroxide, Sodium Carbonate, and Trisodium Phosphate ^
In this paper the writers present results which they obtained, for the most part, in making a comparative study of disinfectants that, might be used by poultrymen, a fact which accounts for the choice of test organisms and various other details of the technic. Although, as the title implies, this work was done chiefly with the hydroxide, carbonate, and phosphate of sodium, the paper also report...
متن کاملSodium bis(ethylenediamine)copper(II) tetracyanidocuprate(I)
The title compound, Na[Cu(en)2][Cu(CN)4], where en represents ethyl-enedi-amine, NH2CH2CH2NH2, crystallizes as a salt with two distinct cations, Na(+) and [Cu(II)en2](2+), and discrete [Cu(I)(CN)4](3-) anions. The anion geometry is tetra-hedral, with angles at the copper atom ranging from 105.0 (1) to 115.4 (1)°. The Cu-C distances are in the range 1.976 (3) to 1.993 (3) Å. The divalent copper ...
متن کاملInactivation of the sodium channel. I. Sodium current experiments
Inactivation of sodium conductance has been studied in squid axons with voltage clamp techniques and with the enzyme pronase which selectively destroys inactivation. Comparison of the sodium current before and after pronase treatment shows a lag of several hundred microseconds in the onset of inactivation after depolarization. This lag can of several hundred microseconds in the onset of inactiv...
متن کاملInfluence of the Sodium Acetate on the Vapor- Liquid Equilibrium of the System Water- Ethanol at Normal Pressure
RESUMO – This work aimed the evaluation of a saline extractive distillation for the ethanol production. Unlike the current method of dehydration of ethanol, which uses a solvent, distillation with the use of salt does not include problems related to toxicity and has lower power consumption, since salt is not volatilized within the distillation column. Many salts had been tested like calcium chl...
