Until recently, the content of salt as NaCl was determined during laboratory analyses largely by a titration method based on the determination of chlorides. This work presents the results of the analysis of the sodium content in two different types of meat product - one from the group white ...
The World Health Organization has recommended since 1920 that salt for cooking be iodized to ensure adequate iodine intake by the population. The frequent appearance of goiter especially in adolescents in some endemic areas of the Dominican Republic prompted a study of iodine content of salt. Concent...
The company representative continues: “Salt content is determined according to China National Standard GB 5009.44-2016 (Determination of Chloride in Foods). In the past we used a manual procedure, the Volhard method, which requires potassium thiocyanate, as well as titration with potassium chromate;...
The aim of the present study was to determine the salt content in eighteen brands of potato crisps commercialized in Portugal, from two different time periods. Material and Methods: Eighteen brands of potato crisps, acquired in local supermarkets in two different seasons (December 2008 and March ...

摘要: The invention deals with the determination of water content in many systems, as the basis for the method, as, for example, in oil- and water- containing emulsions, using adsorbent solids and the temperature rise caused upon adsorption of water thereby....
Complexation titration is commonly used for the determination of aluminum salt. The detailed procedures are as follows. Add excessive amount of EDTA into the solution containing aluminum ions, heat and boil for a moment, and then titrate with the standard solution of zinc. This titration way is ...
