Qualitative Chemical

Analysis

By M. C. SNEED, University of Minnesota

For the sake of simplifying the analytical methods for the beginner, the scheme of analysis provides only for the detection of the more common inorganic ions. The general arrangement of the chapters is, first, a theoretical discussion of underlying principles; second, a discussion of the procedure for the analysis of the ions of a given group; third, experiments whose aim is to give the specific chemical properties of each of these ions; fourth, the procedure by which the ions are separated and detected.

For college students who have completed general chemistry.

NYPE K POTENTIOMETER OUTFIT as used in pH measurements, with two motor-driven shaking device. See Chapters XI and XII of Clarke's "The Determination of Hydrogen Ions".

The uniformly successful and satisfactory operation of the Type K
Potentiometer with its accessories for Hydrogen lon Measurements
has made it a valuable and important part of the equipment of many
laboratories carrying on scientific investigations or controlling pro-
duction processes.

"Electrometric Methods and Apparatus for Determining Hydrogen
lon Concentrations"-Leeds & Northrup Catalogue $75-will help
you determine whether the Type K Outfit is adapted to your work,
or whether some other combination of instruments would serve as
well.

If your work leads you into problems of acidity or alkalinity deter-
minations, or of making accurate titrations under difficult condi-
tions, reading Catalogue S75 may represent time well spent. We
shall be glad to furnish the catalogue.
