Hydrogen Ions (H⁺)

• Hydrogen Ions (H⁺) and Hydrogen Ion Concentration ( [H⁺] ) are important in all aspects of wine making.
  
  
• The Hydrogen Ion Concentration ([H⁺]) of a solution is often represented by the solution's pH .
  
  
• The true pH of a solution however, should be represented by the hydrogen ion's activity (a_H+)
