The amount of substance dissolved in solution is very high . It is difficult to dissolve more substance into solution. 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.. 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. 3.3: Molarity. Describe the fundamental properties of solutions. Calculate solution concentration using molarity. Perform dilution calculations using the dilution equation. Solutions. Remember that . 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:.
