Molecular weight: 315.4662
UN No.: 1759
Appearance: White crystal. Poisonous
Solubility:
Soluble in Water & Carbinol.
(It doesn’t completely soluble in water while it absorbs carbon dioxide quickly from the air into carbonate.)
Solubility: 3.89g/100g water(20°C)
Slightly soluble in Ethanol;
Hardly soluble in Acetone.
If absorb carbon dioxide from the air transform into carbonate, which cannot be completely soluble in water.
100g water dissolved 3.89g in 20° C.
Analysis methods:
standard curve method, standard addition method
The most commonly used analysis method is the standard curve method, which makes up a series of different concentration of standard solution, by adjusting blank solution zero absorption in the same measurement conditions, according to the standard solution concentration and absorbance to draw the absorbance-concentration standard curve, determine the absorbance of the sample solution, using interpolation method on the standard curve to obtain the measuring elements content in the sample.

Application
Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. Its clear aqueous solution is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, as barium carbonate is insoluble in water. This allows the use of indicators such as phenolphthalein or thymolphthalein (with alkaline colour changes) without the risk of titration errors due to the presence of carbonate ions, which are much less basic.
Barium hydroxide is used in organic synthesis as a strong base, for example for the hydrolysis of estersand nitriles.
It has been used to hydrolyse one of the two equivalent ester groups in dimethyl hendecanedioate.
It is also used in the preparation of cyclopentanone,diacetone alcoholand D-Gulonic γ-lactone.
Barium hydroxide is used in a demonstration of endothermic reactions since,
