Infrared Spectra and Characteristic Frequencies of Inorganic Ions

Abstract: use and allows it to dispense no more solvent than is needed when the swab-stick is dipped into it like a pen into an inkwell. Available in 4 oz., 6 oz., and 8 oz. sizes, the price ranges from $3. 50 to $3. 75. This same company also advertises a model No. 10123 1quart "Success" can which dispenses solvent by finger pressure on the valve, which then closes upon release of the pressure, as indicated in the accompanying figure. There is also a plunger can of I-pint size that dispenses solvent by pressure on the plunger. Price for the first type of can is about $8, for the second, about $7.

Iodometric determination of ozone

Abstract: A survey of the literature on ozone for the past 50 years discloses many contradictory and confusing statements concerning methods of ozone determination. This work was undertaken to clarify the situation and establish a reliable method. A chemical method is described, which proved suitable for ozone-oxygen mixtures containing up to 25% ozone. A physical method has been devised for use as a standard of comparison in testing this chemical method. Comparisons have been made with other chemical analytical methods for ozone. This work should clarify the present unsatisfactory situation regarding the chemical analysis of ozone-oxygen mixtures. As the uses for ozone increase, these methods should be of increasing importance.
