Hydrochloric Acid and Barium Hydroxide
2HCl + Ba(OH)2 → BaCl2 + 2H2O
Overview
Hydrochloric acid reacts with barium hydroxide to form barium chloride and water. Barium hydroxide is one of the few strongly basic alkaline earth hydroxides that is significantly soluble in water, making it useful for titrations. The reaction is a standard strong acid-strong base neutralization.

Everyday Example
Barium hydroxide solutions are used in chemistry labs as a strong base alternative to NaOH, particularly for CO₂-free titrations.
Industrial Importance
Barium chloride is used in the production of barium sulfate for medical imaging, in water treatment for sulfate removal, and in heat treatment salts.
