Description

Application

• Self-organized tubular structures as platforms for quantum dots.: This study explores the formation of self-organized tubular structures that can potentially serve as platforms for quantum dots. These structures are formed using copper sulfate solutions in an electrochemical setting, highlighting the versatility and utility of copper sulfate in analytical chemistry applications such as quantum dot technology (Makki R et al., 2014).


• Extended space charge in concentration polarization.: The research discusses the phenomenon of extended space charge within the context of concentration polarization, a critical aspect in electrochemistry and colloid science. Copper sulfate solutions are utilized to study the electrochemical properties and dynamics under various conditions, providing insights into material behavior at the microscale (Rubinstein I et al., 2010).

Analysis Note

Form liquid
Amount-of-substance concentration 0.0995 - 0.1005 mol/L
Measurement uncertainty ± 0.0003 mol/L
Traceability NIST SRM

The concentration is determined by volumetric titration and refers to 20°C.
The amount-of-substance concentration of this volumetric solution is determined with standardized titriplex-III solution (article number 1.08431). The titriplex-III solution is standardized and traceable to a primary standard reference material (SRM) from the National Institute of Standards and Technology, Gaithersburg, USA (NIST SRM 682 Zinc) by means of volumetric standard Zinc (article number 1.02409), certified reference material according to ISO 17034, analyzed by our accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025. The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%.

Note: The titer is a correction factor to correct for variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. For correct titration results it is recommended to determine a titer with the laboratory specific equipment and under laboratory specific conditions directly after opening a new bottle and at regular time intervals.
