Manganometric Titration in Alkaline Solutions. II

Conductivity Titration of Gelatin Solutions

The combination of proteins with acids has been studied by Loeb I and others largely by means of hydrogen electrode measurements. The present work constitutes an attempt to apply the method of conductivity titration to the determination of the combining capacity of a protein for acids. The first work which indicated that the measurement of electrical conductivity could be used in volumetric ana...

Iodimetric Titration of Sulfur Compounds in Alkaline Medium

The possibilities of application of iodine as a titrant in determination of sulfur compounds have been presented. The influence of the reaction medium, the nature of compounds, and the thiol–thione tautomerism on the reaction stoichiometry of sulfur compounds with iodine has been discussed. The conditions of volumetric titration with visual and potentiometric end-point detection and coulometric...

Coulometric Titration with Electrogenerated Tin(II). Titration of Platinum(IV)

Conductivity Titration of Gelatin Solutions with Acids

Titrations have been made, by the conductivity method, of gelatin solutions with hydrochloric and sulphuric acids. The results indicate an end-point at about 8.6 cc. of N/10 acid per gm. of gelatin, or a combining weight of about 1,160. These results are in fair agreement with those previously obtained by the hydrogen electrode method. Better agreement between the two methods was found in the c...
