What is a concentration cell?

The concentration cell is divided into two different sections that are connected by a component to allow electron particles such as a salty bridge. These two half cells contain electrodes and the solutions in each differ in their concentrations. When the concentration cell is activated, the concentrated solution usually dilutes, while the dispersed person adds molecules until both of them are the same. The balance usually approaches, the tension is generated. The strength of this reaction can be measured by calculating the potential of the cell using the mathematical formula called the Nernst equation.

The calculation of the potential of the concentration cell usually requires a voltmeter. The value provided by a tool that can be positive or negative can then be inserted into the equation and used with the level of concentration to determine the potential. The electrons flow from one substance to the other in a concentration cell. The section that loses particles is called Oxidstrana Ation, while the page of reduction gets them.

Metal parts are often used in these types of cells andTheir different areas can be exposed to different concentrations. Some metal parts may have greater electrical potential than others, which can cause corrosion. While the concentration cell can be cleaned to prevent this, it is often difficult when the system is placed in the soil, for example.

Corrosion may occur due to metal ions. If the cell contains or is exposed to water, it is not sealed or there is no protective coating, the areas near the high level of metal ions may corrode. Uneven oxygen concentrations that can occur on metal surfaces underwater can lead to corrosion where gas levels are low. Points between neighboring parts and wood, rubber or plastic near the metal surface are usually where degradation occurs. The active passage of the concentration cell develops when oxygen and passive film are pierced under a layer of salt, causing the mine to the metal.

oncentration cells are often used as meters for measuring acidity and alkalinity of the soil. They usually have one end exposed to the soil and the other end contained in potassium chloride solution. Then it is possible to compare these two measurements. In general, the higher the voltage is made, the more acidic the sample. The concentration cell can also be used to analyze chemicals as well as testing different materials for susceptibility to corrosion.
