Potentiometric titration of viscose

Journal of Polymer Science, 1948
AbstractA new method is investigated to determine by means of potentiometric titration the degree of ripening of viscose. It is found that when the e.m.f. of a characteristic inflection in the potentiometric titration curve is plotted against a measure of the degree of viscose ripening a sharp minimum occurs at a point corresponding to the optimal ...

A recording potentiometric/spectrophotometric titrator

Analytical Biochemistry, 1967
A system for the simultaneous recording of spectrophotometric and potentiometric titrations at constant temperature is described. Application to the determination of the pK′ of the ionization of the iron-bound water molecule in horse and in sperm whale ferrimyoglobin and to the study of the attachment of nickel mesoporphyrin to human apohemoglobin A is

Potentiometric titration studies on globular proteins

Biopolymers, 1972
AbstractA power series method was applied to solve the Poisson‐Boltzmann equation for the spherical polyelectrolyte model and numerical calculation with an electronic computer was performed to obtain surface electric potential on rigid globular proteins.

Potentiometric titration of plutonium

Journal of Radioanalytical Chemistry, 1978
In the potentiometric titration of plutonium(III), it has been customary to take the equivalence point as the inflection point on a plot of potential vs. volume of titrant.1 That the stoichiometric end point corresponds to the inflection point does not seem to have been theoretically demonstrated, however.

Computer-Assisted Potentiometric Titrations

1975
The Nernst equation is the basis for carrying out potentiometric measure­ments. For a generalized redox reaction $$ aA\; + \;bB\; \rightleftarrows \;c{\kern 1pt} C\; + \;dD $$ (14–1) the potential of the cell is given by $$ E\; = \;E_{cell}^0\; - \;\frac{{RT}}{{nF}}{\kern 1pt} \ln {\kern 1pt} \frac{{{{\left( {{a_c}} \right)}^c}{{\left ...
