Is barium hydroxide soluble? What is its application?

Barium hydroxide, white powder or colorless and transparent crystal, is a kind of inorganic salt. It is also known as anhydrous barium hydroxide. Is barium hydroxide soluble? It is soluble in water and methanol, but insoluble in acetone. 

Barium hydroxide is decomposed into barium oxide at temperatures of 600 degrees Celsius and above. It quickly absorbs carbon dioxide from the air into carbonate, which is not entirely soluble in water. Barium hydroxide is one of the few alkalis soluble in water, and other alkalis soluble in water are sodium hydroxide, lithium hydroxide, and so on.

The chemical properties of barium hydroxide

After discussing the question “Is barium hydroxide soluble”, we will give a simple introduction to the chemical properties of barium hydroxide. Due to its strong alkalinity, barium hydroxide is corrosive to skin and paper. Barium hydroxide is eco-friendly, but it contains a strong alkaline, so we should keep it away from animals and plants.

The alkalinity of Barium hydroxide is the strongest among alkaline earth metals, which can turn phenolphthalein solutions red and purple litmus blue. It can be neutralized with acid, and it reacts with sulfuric acid then forms barium sulfate precipitation.

 The application of barium hydroxide

Is barium hydroxide soluble? Does its solubility affect its application? Let’s explore this answer together.

1. Barium hydroxide can be applied as a raw material for producing pesticides, soap, and other items because of its highly corrosive and alkaline. It can be used for beet saccharin production and can soften hard water, descale boiler, and so on. In addition, it also can be used for organic synthesis and preparation of barium salt.

2. Barium hydroxide is used as a catalyst to compose phenolic resin. The polycondensation reaction is easy to control, the obtained resin has low viscosity and fast curing speed, and the catalyst is easy to remove. It also can be used as a catalyst for water-soluble urea-modified phenol-formaldehyde adhesive, the cured product is light yellow, and the residual bivalent barium salt in the resin does not affect the dielectric property and chemical stability.

3. Barium hydroxide is used as an analytical reagent and is also used to separate precipitated sulfate and make barium salt, determine carbon dioxide in the air, and quantify chlorophyll.

How to prepare barium hydroxide?

This paper introduces a method for preparing barium hydroxide with barium carbonate. The steps are as follows. First, the mineral containing barium carbonate is ground into mineral powder, and then the mineral powder is calcined at high temperature under the state of suspended flow to obtain the calcined ore containing barium oxide. After the calcined ore is immersed in water, the solution of barium hydroxide is formed, and then the solution is separated from solid and liquid, then cooled and crystallized to obtain the barium hydroxide product.

Emergency treatment when barium hydroxide leaks 

If barium hydroxide leaks, we should insulate the contaminated area of leakage and don’t let people enter. Do not touch spills directly. In case of small leakage, we should avoid dust and collect it in a dry, clean, covered container with a clean shovel. If there is a large number of leaks, cover it with plastic sheets and canvas to reduce flying. It is then collected, recycled, or transported to a waste disposal site for disposal.

First aid measure when barium hydroxide is contacted by mistake

If skin contacts barium hydroxide, we need to take off contaminated clothing and rinse the skin thoroughly with soapy water and clean water.

If the eye contacts barium hydroxide, lift the eyelids and rinse with running water or saline, then seek medical attention.

If someone sucks in barium hydroxide, quickly leave the scene for fresh air. Keep your airway clear. When breathing is not smooth, provide oxygen quickly. If breathing stops, give artificial respiration immediately, then see a doctor. 

If someone ingested barium hydroxide, drink enough warm water, induce vomiting, wash the stomach with 2% ~ 5% sodium sulfate solution, and induce diarrhea. 

Conclusion: 

This brings us to conclude our essay on the topic of "Is barium hydroxide soluble”. Barium hydroxide is easily soluble in water and methanol, but it has poor integration with acetone. And it has wide use in many different fields. For example, it can be used to produce pesticides and soap. In the catalyst field, it can be used to composite phenolic resin as a catalyst.
