What is BaCl2? Is there a precipitate?

What is the chemical compound BaCl2? Does Bal2 precipitate? Knowledge chemistry This inorganic will be explained in detail by thuvienhoidap.net in this article.


What is BaCl2 concept?



  • BaCl₂ chemical name Barium Chloride is an inorganic salt made up of Barium cations (Ba⁺) and chloride anion (Cl⁻). It is also named Barium chloride or Barium Muriate.

  • It is a white, water-soluble, solid chemical compound that is hygroscopic and produces a light green color when exposed to flame. At standard conditions, barium chloride exists as a white crystalline solid

  • Barium salt is widely used in industry and BaCl2 salt is soluble and highly soluble in aqueous solution.


Physical properties of BaCl2



  • BaCl2 is a white, odorless crystalline powder. In the solid state BaCl2 has a white orthorhombic crystal form.

  • Barium Chloride is dispersible in water. It is determined to dissociate into chloride anion and barium cation when it is dissolved.

  • At a temperature of 20 ℃, the solubility of Barium chloride in water is close to 358 grams per liter.

  • Slightly soluble in hydrochloric acid and nitric acid.

  • Hardly soluble in ethanol and ether.

  • BaCl2 is highly hygroscopic.

  • Density: 3,856g /cm3

  • Melting point: 960 °C

  • Boiling point: 1560

  • Molecular Mass: 208.23 g/mol


Chemical properties of BaCl2


Because it is a chloride salt, BaCl2 has the characteristic properties of chloride salts such as hydrolysis reaction, reaction with acid, salt solution...

a – Electrolysis of BaCl2


Since BaCl2 contains the metal element Ba, which is metal active, so in order to decompose this salt, we must apply solution electrolysis.



b – React with acidic solution


Because it is a soluble salt, BaCl2 can react with many strong acids such as H2SO4.



  • BaCl2 + H2SO4 → BaSO4 + 2HCl


Note that BaCl2 does not react with 2 acids, HCl and HNO3, because the product formed has no precipitate or volatile matter.



  • BaCl2 + HCl → HCl2 + BaCl


We see that the products formed are two substances, BaCl and HCl2, which cannot precipitate, so this reaction cannot occur.


c – Reaction with basic solutions

BaCl2 reacts with a variety of basic solutions to form new salts and new bases.


For example, BaCl2 reacts with NaOH, KOH



  • BaCl2 + 2NaOH → Ba(OH)2 + 2NaCl

  • BaCl2 + 2KOH → Ba(OH)2 + 2KCl


d – React with salt solution


BaCl2 also works with many soluble salt solutions such as AgNO3, Na2SO4, MgSO4



  • BaCl2 + 2AgNO3 → Ba(NO3)2 + 2AgCl

  • BaCl2 + Na2SO4 → BaSO4 + 2NaCl

  • BaCl2 + Na2CO3 → BaCO3 + 2NaCl

  • BaCl2 + MgSO4 → BaSO4 + MgCl2

  • BaCl2 + K2SO4 → BaSO4 + 2KCl


e – Does BaCl2 precipitate?


The answer is yes, BaCl2 produces a white precipitate.


How to recognize BaCl2


Add a few drops of H2SO4 acid solution to BaCl2 solution if a white precipitate appears, insoluble in acid, it is BaCl2.



  • BaCl2 + H2SO4 → BaSO4 + 2HCl

Is BaCl2 a strong or weak electrolyte?


The answer is that BaCl2 is a strong electrolyte because when dissociating, two ions are obtained, Ba2+ and Cl-, which have strong electrolytes.


How to prepare BaCl2


There are two ways to prepare BaCl2 including:


How to prepare BaCl2 in industry


Barium chloride can be produced via a two-step reaction from barium sulfate to barium sulfate which reacts with HCl to give barium chloride.



  1. BaSO4 + 4C → BaS + 4CO

  2. BaS + 2 HCl → BaCl2 + H2S


How to prepare BaCl2 from BaCO3 . salt


Can use BaCO3 react with hydrochloric acid to form BaCl2

  • BaCO3 + 2HCl → H2O + CO2 + BaCl2


Applications of BaCl2



  • The main industrial application of BaCl2 is in the cleaning of brine solutions used in caustic chlorine plants.

  • This compound is also used in the case of steel hardening and in the production of heat treatment salts.

  • Barium chloride is used in the pyrotechnics industry because of its green color. It is also used to treat salts generated by heat.

  • It is used in the manufacture of various barium salts.

  • It is used in a number of processes in the oil and gas industry.

  • It is used in the production of oil lubricants, PVC stabilizers, barium chromate and barium fluoride.
