Do the Elements Sign their Name in the Spectral Lines?

Authors: Tzimon Barto
Comments: 9 Pages.

My study concerns the elusive patterns of the chemical elements' spectral lines as they appear in the region of that spectrum visible to the naked eye.A musical chromatic scale is superimposed over the standard system measuring the frequencies of each element's spectra.The interval between the base of the measurement - "0" - and that area on the chromatic scale where the intensity of an element's spectra is at its weakest and at its strongest provide the clues necessary for determining a pattern ultimately found in 90 out of the 98 naturally occurring elements. My short paper on the subject reveals exactly how this conclusion is reached. The data I used are tables provided by the NIST Atomic Spectra Database and NIST Standard Reerence Database.

Determination of the Ion Mobility in IPA by the Statistical Method of Finding Values of the Components of Binary Sums

Authors: Yu. E. Zevatskiy
Comments: 8 Pages.

The values of limiting mobilities of 29 organic and inorganic ions in isopropyl alcohol were determined by the method of the nonlinear regression. The experimentally determined values of the molar specific limiting conductivity of salts, acids and bases obtained by the conductometric and potentiometric measurements in isopropyl alcohol.

Application of a Conductometric Method to Research the Protolytic Equilibria in Isopropyl Alcohol. Sodium Hydroxide is Used as a Titrant

Authors: A. V. Selitrenikov, Yu. E. Zevatskiy
Comments: 20 Pages.

The existing method to determine the dissociation constants of weak electrolytes using the direct conductometry and titration in aqueous solutions was successfully applied to the study in isopropyl alcohol medium. The sodium hydroxide was firstly applied as a titrant for the conductometric titration. Obtained values of dissociation constants of such electrolytes as: Н2СО3, HСlO4, NaOH, NaClO4, NaHCO3 in isopropyl alcohol allow to use them in potentiometric and spectrophotometric studies and ionic equilibria modeling in the presence of carbonic acid.
