2 points 11 My Notes Acidity of solution is determined by the concentration C of hydrogen ions in the solution (measured in moles per liter of solution). Chemists use the negative of the logarithm the following formula. of the concentration of hydrogen ions to define the pH scale, as shown pH log (C) Lower pH values indicate a more acidic solution.
