concentration, in chemistry, measure of the relative proportions of two or more quantities in a mixture mixture, in chemistry, a physical combination of two or more pure substances (i.e., elements or compounds). Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. What does concentration mean? In chemistry, concentration is how much of a substance is mixed with another substance.. Table of Content. concentration, in chemistry, measure of the relative proportions of two or more quantities in a mixture mixture, in chemistry, a physical combination of two or more pure substances (i.e., elements or compounds). In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Related Terms & Definitions. Meaning of concentration. In chemistry, the concentration of a solution is the quantity of a solute that is contained in a particular quantity of solvent or solution. concentration [kon″sen-tra´shun] 1. increase in strength by evaporation. Definition of concentration in the Definitions.net dictionary. What is a Solution? Chemists use many different methods to define concentrations, some of which are described in this section.

In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Common examples of solutions are the sugar in water and salt in water solutions, soda water, etc. Molarity is used to express the concentration of a solution. Also known as molar concentration, molarity is the number of moles of solute (the material dissolved) per liter of solution.. hydrogen ion concentration see hydrogen ion concentration. Concentration definition, the act of concentrating; the state of being concentrated. Knowing the concentration of solutes is important in controlling the stoichiometry of reactants for solution reactions. Here are some related terms and definitions we found for this term.

These variations on percentage concentration are used in chemistry and biology when making up solutions and have the following meanings. In chemistry, "concentrated" refers to a relatively large quantity of substance present in a unit amount of a mixture.Usually, this means there is a lot of a solute dissolved in a given solvent.A concentrated solution contains the maximum amount of solute that can be dissolved. 2) The relative abundance of a solute in a solution. In pharmacology, the term concentration refers to the strength of a pharmaceutical preparation.

To concentrate a solution, one must add more solute, or reduce the amount of solvent.

Concentration cell definition, a galvanic cell consisting of two electrodes of the same metal each in different concentrations of a solution of the same salt of that metal. 2. the ratio of the mass or volume of a solute to the mass or volume of the solution or solvent. See more. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution . Activity coefficient, in chemistry, the ratio of the chemical activity of any substance to its molar concentration.The measured concentration of a substance may not be an accurate indicator of its chemical effectiveness, as represented by the equation for a particular reaction, in which case an activity coefficient is arbitrarily established and used instead of the concentration in calculations. In chemistry, the concentration of a solution is the quantity of a solute that is contained in a particular quantity of solvent or solution. In chemistry, the number of molecules or ions in a given volume of a substance, expressed as moles of solute per litre of solution (molarity). Concentration Gradient Definition. Solution - Properties of Solution. 2. In chemistry, concentration refers to the amount of a substance in a defined space. Definition of concentration. See more.
