This is a phenomenon which can occur when a metal is in contact with an environment that contains different concentrations of electrochemically active constituents at different points on the surface of the metal and thereby maintains differences of electrical potential on different parts of the surface of the metal.

List 6 types of corrosion that effect aircraft?
Galvanic, pitting, concentration cell, intergranular, stress cracking, Uniform etch, crevis corrosion
Why anodic inhibitors are not satisfactory?
there is a certain critical concentration of solution above which inhibition may be experienced... when an insufficient concentration is used all the anodic areas may not be covered, as a result it leads to increase in current density at that place......hence, it can be dangerous..if not used in right concentration...
Which component, the anode or cathode, is more prone to corrosion in a galvanic cell?
The anode is more prone to corrosion in a galvanic cell.
Acids on glavanized nails?
Corrosion, depending on the type and concentration of the acid.
Is corrosion is a reversible cell reaction or irreversible cell reaction?
Corrosion is typically considered an irreversible cell reaction. It involves the degradation or deterioration of a material due to chemical or electrochemical reactions with its surroundings, leading to a loss of material and structural integrity. Once corrosion occurs, it is difficult to reverse the process completely.
What is the difference in chloride concentration inside and outside the cell?
The chloride concentration is higher outside the cell than inside the cell.
How does solute concentration affect diffusion osmosis?
Solute concentration affects diffusion and osmosis by creating a concentration gradient. Higher solute concentration outside the cell will cause water to move out of the cell, leading to a decrease in cell volume. Lower solute concentration outside the cell will cause water to move into the cell, increasing its volume.
What does a difference in concentration in a cell create?
a concentration gradient
What if a cell has a lower concentration outside the cell?
There are two basic ways that individual molecules can enter (or leave) a cell.1. Diffusion. This is the movement of particles from a region of high concentration to a region of low concentration. So if the concentration of the molecule is higher outside the cell it can enter by diffusion. However diffusion can only take place down a concentration gradient ie from a high to a low concentration.2. Active transport. This is the movement of particles against their concentration gradient (ie from a low to a high concentration), using energy provided by the cell (ie ATP produced by respiration). So if a molecule is at a higher concentration inside the cell it can only be absorbed by active transport.
The concentration of potassium ions inside the cell is usually what?
The concentration of potassium ions inside the cell is typically higher than it is outside the cell. This concentration gradient is maintained by the sodium-potassium pump, which actively transports potassium ions into the cell. This imbalance in potassium concentration is important for various cellular processes, such as maintaining the cell's resting membrane potential.
As the concentration of molecules outside a cell increases more molecules will enter the cell?
Yes, this process is known as osmosis. Water moves from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell) to balance the concentration levels. This causes more molecules to enter the cell as the concentration difference increases.
What different solutions can cells be in and what happenes to them?
There are three different types of solutions you can place a cell in: hypotonic (concentration of solution less than concentration of cell), isotonic (equal concentrations) and hypertonic (concentration of solution greater than concentration of cell). In a hypotonic solution, the cell will accumulate water (in an attempt to equalize the concentration difference) and will eventually rupture from the water pressure inside the cell. In an isotonic solution, the cell will do nothing. In a hypertonic solution, the cell will shrivel as the water exits the cell to dilute the solution to the same concentration as the cell. This will cause the cell to die.
