WebThe pH scale measures the concentration of hydrogen ions in a solution. The following equation gives the pH: pH = - log ( [ H +]) A pH below 7 is acidic, whilst a pH above 7 is alkaline. A neutral solution has equal concentrations of hydrogen and hydroxide ions. Strong acids and bases dissociate completely in solution. WebSep 9, 2024 · The term “Molarity” indicates that a solution’s concentration is in units of moles per liter. A one molar solution (1 M) contains one mole of solute within each liter of that solution. Reagents used in the laboratory will often be labeled with their concentrations expressed in terms of molarity.
