Total Acidity

• The total acidity of a solution is a measure of all the hydrogen ions (H⁺) of both the fixed and volatile acids present.
  
  These include -
  • the potential H⁺ (hydrogen ions) able to be released
    
    
  • plus those H⁺ already released, existing as free H⁺ in solution.
    
    
• Total acidity is a more accurate representation of the acid concentration then titratable acidity , however it is difficult to measure.
  
  Hence the easier to measure titratable acidity is used to approximate total acidity
