The precipitation titration of sodium chloride with electrogenerated silver ion was studied. The production of a precipitate of silver chloride had a significant effect on the titration results because the precipitate involved unreacted chloride or unreacted silver ion. The accuracy of the method was investigated by changing the introduction time of a sodium chloride solution to the coulometric...

background: interaction between local anesthetic solution, lidocaine hydrochloride (with and without adrenaline), and root canal irrigants such as sodium hypochlorite (naocl), ethylene diamine tetra-acetic acid (edta), and chlorhexidine (chx) has not been studied earlier. hence, the purpose of this in vitro study was to evaluate the chemical interaction between 2% lidocaine hydrochloride (with ...

Nickel hydroxides are widely used as electrochemically active substances in alkaline batteries and hybrid supercapacitors; they can be for electrocatalysis, electrochemical sensors, pigments. Knowledge of the formation mechanism nickel is necessary developing optimizing targeted synthesis methods. The thermal effects processes hydroxide from nitrate were studied by calorimetry method. precipita...

LTHOUGH THE FLAME PHOTOMETER jS the method of choice for the determination of serum sodium in most large, well-equipped laboratories, there remains a place for an alternative procedure which can be used in laboratories too small to afford a flame photometer, or which can be carried out by an intern, resident, or general laboratory technician at night or at other times when the photometer operat...

Simulation of the Liesegang pattern formation in low concentration gradient is presented using concentration perturbation in a deterministic model. The precipitation process is based on ion-product supersaturation theory (Ostwald's model). In the classical experiments with high initial concentration gradients, appearance time and locations of the band formation are well reproducible. Decreasing...

The separation of inorganic precipitates with similar solubility products is a challenging task in chemical engineering. We present computational fluid dynamics study precipitation reaction flow-driven reactor. For reference study, the cobalt(II)-copper(II)-oxalate system selected, where occurs simultaneously and difference within an order magnitude as shown experimentally. general description ...
