Recent studies dealt with the influence of hydroxyethylmethyl cellulose (HEMC) and hydroxypropylmethyl cellulose (HPMC) mortar formulations HEC influence on cement hydration measured by condu ctometry Conductometry is a powerful tool for monitoring the hydration kinetics. Recently Asked Questions The transactions of the Speedy Delivery Service are recorded in the general The main principle involved in the coulometry is the measurement of the quantity of the electricity which is directly proportional to the chemical reaction at the electrode. A DRM capable reader equipment is required. In usual analytical chemistry practice, the term conductometry is used as a synonym of conductometric titration, while the term conductimetry is used to …Conductimetry is a useful technique to study this process because complex formation is accompanied by the release of ionic specie (in our case NaCl) with different mobility in the medium, consequently resulting in increase of conductivity.
