Electroanalytical methods are a class of techniques in analytical chemistry which study an analyte by measuring the potential and/or current in an electrochemical cell containing the analyte.
Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change.
Electrochemical cells – generates electrical energy from chemical reactions; Electrotyping – a process used to create metal copies of designs by depositing metal onto a mold using electroplating; Electrowinning – a process that extract metals from their solutions using an electric current
In his laboratory he had learned to alloy the amalgamated zinc of Sturgeon with mercury. His version was the first of the two-fluid class battery and the first battery that produced a constant reliable source of electric current over a long period of time. William Grove produced the first fuel cell in 1839. He based his experiment on the fact ...
In electrochemistry, a salt bridge or ion bridge is an essential laboratory device discovered over 100 years ago. [1] It contains an electrolyte solution, typically an inert solution, used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell.
Voltammetry is the study of current as a function of applied potential. Voltammetric methods involve electrochemical cells, and investigate the reactions occurring at electrode/electrolyte interfaces. [4] The reactivity of analytes in these half-cells is used to determine their concentration.
In electrochemistry, cyclic voltammetry (CV) is a type of voltammetric measurement where the potential of the working electrode is ramped linearly versus time. Unlike in linear sweep voltammetry , after the set potential is reached in a CV experiment, the working electrode 's potential is ramped in the opposite direction to return to the ...
Electrochemical stripping analysis is a set of analytical chemistry methods based on voltammetry [1] or potentiometry [2] that are used for quantitative determination of ions in solution. [3] Stripping voltammetry (anodic, cathodic and adsorptive) have been employed for analysis of organic molecules as well as metal ions.
