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

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.

BaSO4 + 4C → BaS + 4CO

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.
