Meaning of Concentration
What is Concentration:
Concentration is the ability to keep your attention on something particular or specific.
Concentration is one of the fundamental skills for learning or the knowledge process.
Concentration is related to attention, both stages being the same process. Attention precedes concentration. Attention selects what is considered most important and concentration is the focus of attention on a certain objective.
See also Attention.
Concentration also refers to the degree of accumulation or quantity of people, objects or factors, for example, the concentration of the population in urban places is greater than in rural areas.
Concentration in chemistry
In chemistry, concentration is the relationship between the amount or volume of solute and the amount of solution. The more solute, the higher the concentration in a solution.
The concentration in a solution changes with any action or set of actions in relation to the amount of water added or removed, the amount of solute added, and the type of solute.
It is important to note that the color of the chemical solution is related to the concentration. Generally, the more subdued the color, the lower the concentration.
See also Chemical solution.
Concentration in chemistry is expressed in three ways:
- Molarity: it is the most used form and is calculated by dividing the moles of the solute (quantity) by the volume (in liters) of the solution.
- Molality: calculated by dividing the moles of the solute by the mass (in kilograms) of the solvent.
- Molar fraction: it is obtained from the moles of solute divided by the total moles.
See also Chemical concentration.
Concentration is also expressed in daily life by:
- The concentration in mass between volume (g / L), for example, the minerals measured in grams in a liter of water.
- The concentration in percent of mass C (% m / m), that is, the percentage of mass that exists.
- The concentration in percent by volume C (% V / V) is commonly used to measure the alcoholic strength of beverages.
See also Solute and solvent.
Concentration camps are detention or confinement centers where people are imprisoned and tortured. The most common case of concentration camps are those known at the time of the Holocaust, where people were locked up and exterminated by Nazi ideology.
