Barium Hydroxide Hydrate Extra Pure
Original price was: $ 18.00.$ 17.34Current price is: $ 17.34.
Barium Hydroxide Hydrate Extra Pure is a high-purity, white crystalline compound containing eight molecules of water of crystallization. It is widely used in laboratory chemistry as a strong base in titration, qualitative analysis, and inorganic synthesis. Its high solubility in water and strong alkalinity make it valuable for neutralization reactions, preparation of barium salts, and as a reagent for detecting sulfates, carbonates, and phosphates. In analytical applications, it is often used where precise pH control and minimal contamination are critical. The extra pure grade ensures consistent performance in high-accuracy experiments. It should be handled with care and stored in a tightly sealed container in a cool, dry place, as it is caustic and sensitive to carbon dioxide in the air, which can lead to carbonate formation.
Barium Hydroxide Hydrate Extra Pure

- Strong Alkali for Acid–Base Titrations
- Functions as a standard strong base, like NaOH or KOH, particularly useful in titrations where sodium contamination must be avoided (e.g., gravimetric sulfate analysis).
- Reagent for Sulfate Ion Determination
- Used to precipitate barium sulfate (BaSO₄) from solutions containing SO₄²⁻ — ideal for gravimetric sulfate analysis in water or fertilizers.
- Alkalizing Agent in Chemical Reactions
- Provides a high pH environment for hydrolysis, saponification, or other base-catalyzed reactions.

- Reacts with CO₂ to form insoluble barium carbonate — used in gas detection and quantitative CO₂ absorption studies.
- Preparation of Other Barium Compounds
- Acts as a precursor for the lab-scale synthesis of barium salts, such as BaCl₂, Ba(NO₃)₂, and Ba(CH₃COO)₂, through neutralization with appropriate acids.
Secondary Uses
- Educational Demonstrations of Strong Base Behavior
- A non-sodium hydroxide alternative for demonstrating alkali metal reactivity, hydroxide solubility, and exothermic dissolution.
- Use in Analytical Chemistry for Weak Acid Titration
- Employed in titrating weak organic acids, such as acetic or oxalic acid, in biochemical or food chemistry contexts.
- Study of Crystallization and Hydrate Behavior
- Serves as a model for studying hydrated salt structure, deliquescence, and thermal decomposition in physical chemistry labs.
- Reagent in Organic Chemistry Reactions
- Occasionally used in aldol condensations, eliminations, or saponification reactions where a solid, less hygroscopic base is desired.
- Base in Specialized Metal Precipitation Reactions
- Employed in selective precipitation of transition metals or amphoteric hydroxides, depending on pH and ionic strength.
