Used in water-base muds as a source of hydroxyl ions to control pH

Caustic soda is used to maintain or increase pH. Increasing pH with caustic soda precipitates magnesium (Mg2+) and suppresses calcium (Ca2+) in high-hardness waters such as seawater, reduces corrosion, and neutralizes acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S).
