PPT-Molar Concentration Knowing the concentration of a solution provides a way to find how

Concentration The amount of a specific substance in a known volume of solution Concentrated Solutions The amount of substance dissolved in solution is very high It is difficult to dissolve more substance into solution.

LG: I can perform concentration calculations involving units commonly used in consumer products. Percent Concentration. Many consumer products report the percent of solute relative to the total amount of solution; these concentrations may involve weights and volumes. Most solutions are stored in concentrated form and diluted for use when required. . To dilute to the required concentration we must extract the number of moles required from the stock solution and place them in the new flask. . Solutions Expressed as percent. The term . percent. . is Greek for . per 100. . When concentration is expressed in terms of percent, the numerator is the amount of solute and the denominator is 100 units of total solution.. Solutions and Concentration What is a solution? Homogeneous mixture of solute and solvent Solute: substance dissolved Often a solid Solvent: substance in which the solute is dissolved Usually a liquid LG: I can perform concentration calculations involving units commonly used in consumer products. Percent Concentration. Many consumer products report the percent of solute relative to the total amount of solution; these concentrations may involve weights and volumes. There are H. +. and OH. - . ions in all solutions. In neutral solutions: [H. +. ] = [OH. -. ] = 1 x10. -7. M. If [H. +. ] >1 x10. -7. M, solution is acidic. Learning Objectives:. Calculate the amount of substance in moles, using solution volume and concentration . Describe a solution’s concentration using the terms concentrated and dilute. . Key Words:.
