PPT-Molar concentration and dilution

Lesson 6 Concentration Concentration Is a measure of the amount of substance soluteusually solid that exists in a volume of solution solvent Concentration The amount of solute in a solution. From Liquids. (More accurately, from stock solutions). Making molar solutions from liquids. Not all compounds are in a solid form. Acids are purchased as liquids (“stock solutions”). Yet, we still need a way to make molar solutions of these compounds.. An introduction to dilutions. Dilutions are fractions. When we add water to orange juice concentrate to make orange juice for breakfast, . we are making a dilution. .. The dilution that we have made can be determined by the expression:. Salman Ahmad.

Solutions. Solution: . a homogenous mixture of two or more substances in the same phase.. Solute: . substance dissolved in another substance (the solvent). Solvent: . substance that dissolves a solute, resulting in a solution. In a dilution, a solvent, usually water, is added to a solution, which increases its volume and decreases the concentration of the solution.

The amount of substance dissolved in solution is very high . It is difficult to dissolve more substance into solution. Ben Cope. Office of Environmental Assessment. EPA Region 10. January 2013.
