1. A preparation made by extracting a crude drug, precipitating it from the solution, and drying. 2. Increasing the amount of solute in a given volume of solution by evaporation of the solvent. 3. The quantity of a substance per unit volume or weight. In renal physiology, symbol U fo...
As the concentration of a solution decreases, what happens to the values of Ka and Kb? Classification of Concentration: Concentration, in chemistry, is the amount of a certain substance that can be found within a space such as a container. It is often expressed in units...
However, in chemistry, the concentration of solutions is often expressed as a “molarity” (a molar concentration), which is defined as the number of moles of solute divided by the number of liters of the solution. This gives you a value in moles per liter, where one mole of a substance...
PURPOSE:To carry out the collection of solute into a receiving vessel with a minute volume quickly and automatically without lowering the evaporation temp. of a solvent, by a method wherein the known amount of a solution is dripped as a minute liquid droplet form and the temp. variation of ...

The meaning of CONCENTRATION is the act or process of concentrating : the state of being concentrated; especially : direction of attention to a single object. How to use concentration in a sentence.
Ions in the soil solution can form a number of species due to hydrolysis, complexation, and redox (see Chapter 8) reactions. Hydrolysis reactions involve the splitting of a H+ ion from a water molecule which forms an inner-sphere complex with a metal ion (Baes and Mesmer, 1976). The ...
What is the concentration of the solution that results from diluting 45.0 mL of a 1.04-M solution of {eq}CH_3OH {/eq} to 0.500 L? Diluting a Solution: When diluting a solution, we are effectively decreasing the concentration of the solute by addin...
