Various Concentration Terms Concentration is defined as amount of solute per amount of solution or solvent. The "amounts" you chose is what gives each concentration term it's own uniqueness. percent conc = (mass of solute)/(mass of solution) x 10 2 ppm = (mass of solute)/(mass of solution) x 10 6 ppb = (mass of solute)/(mass of solution) x 10 9 molarity = (mol of solute)/(liters of solution) For the rest of this page, concentration is assumed to be in MOLARITY. Molarity Concentration is often depicted with square brackets around the solute of interest. concentration of hydrogen ion is depicted as [H + ]. The concentration is assumed to be molarity (mol/L or mmol/mL). Concentration is also sometimes shown as molarity with an italicized capital "M" and a subscript for the solute. The concentration of hydroxide would be M OH - . Unfortunately, italics are not always used - sometimes, like here, the non-italized version just looks better (M OH - ). Dilutions - adding more solvent (ie. water) to an already
