The Electrical Double Layer01:30

The Electrical Double Layer

195
In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...

Processes at Electrodes

The electrode interacts with ions in the electrolyte solution at its interface. The rate of oxidation and reduction depends on the speed at which electrons can transfer through this interface. As ions attach to or leave the electrode surface, the electrode acquires a charge, and an electrical potential forms across the interface, making the process more difficult to reach equilibrium. The charge on the electrode affects the local ion concentrations in the solution, though thermal motion...

Potentiometry: Membrane Electrodes

Membrane electrodes, also known as p-ion electrodes, use membranes that selectively interact with free analyte ions, generating a potential difference across the membrane. The resulting membrane potential, known as the asymmetry potential, is not zero even when analyte concentrations on both sides of the membrane are equal. The membrane's response is typically not selective to a single analyte but proportional to the concentration of all ions in the sample solution capable of interacting at...

Standard Electrode Potentials

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Reference electrodes serve as a stable reference point for potentiometric measurements, while indicator and working electrodes react to variations in the composition of a solution.
The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...

Two-dimensional Gel Electrophoresis01:22

Two-dimensional Gel Electrophoresis

8.4K
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method involves protein separation by two dimensions, mass and charge, making it more accurate than one-dimensional gel electrophoresis.
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.
Biological samples, such...

  • Electrochemistry
  • Materials Science
  • Thermoelectric Devices

Background:

  • Electrolytes with additives like gelatin can alter thermoelectric device properties.
  • The temperature coefficient (α) of electrode potential (E) is a critical parameter in thermoelectric devices.

Purpose of the Study:

  • To investigate the specific effect of gelatin on the electrode potential (E) in electrolytes.

Main Methods:

  • Systematic experiments were conducted using various electrolytes.
  • Electrode potential (E) measurements were performed in the presence and absence of gelatin.

Main Results:

  • Gelatin in electrolytes significantly reduces the electrode potential (E) by several hundred millivolts.
  • This reduction was observed specifically due to contact with gelatin, not other substances mentioned previously.

Conclusions:

  • The positive surface charge of gelatin is identified as the primary cause for the observed reduction in electrode potential (E).
  • Understanding this interaction is crucial for optimizing thermoelectric device performance and electrolyte formulation.
