The typical pH range is 0-14 but actual pH levels can exceed these theoretical limits. pH adjustment alters the pH or Potential Hydrogen by adding a pH reagent such as using acid to drive pH downward or using a caustic or other alkaline substance to drive pH upward. Sulfuric acid and sodium hydroxide (caustic) are most commonly used.
