Ammonium Chloride and Barium Hydroxide Reaction | NH4Cl + Ba(OH)2

When ammonium chloride (NH4Cl) is heated with barium hydroxide ( Ba(OH)2 ), ammonia gas is released and colorless solution is given as another product. NH4Cl is a weak acid and barium hydroxde is a strong base.

NH4Cl + Ba(OH)2 → NH3 + BaCl2 + H2O

Barium chloride reacts with aqueous barium hydroxide and produce ammonia gas, barium chloride and water as products. Ammonia dissolve very well in water. But, when mixture is heated ammonia's solubility decreases and comes out from the solution. When this happens, you should be careful to avoid inhaling ammonia gas because ammonia is a very toxic gas and can cause to severe injuries to humas..

When an ammonium salt is heated with a strong alkali, ammonia gas is emitted.

As ammonium salt, ammonium chloride, ammonium nitrate, ammonium sulfate and more can be used. As well, aqueous NaOH, KOH, Ba(OH)2 are used as alkalis. You can test ammonia gas emission from different experiments.

NH4+ + OH- → NH3 + H2O

Balanced chemical equation

2NH4Cl + Ba(OH)2 → 2NH3 + BaCl2 + 2H2O

Two ammonium chloride moles react with one mole of barium hydroxide and produce two moles of ammonia, one mole of barium chloride and two water moles.

Questions asked by students.

Is there a precipitation forming when barium hydroxide reacts with ammonium chloride

products of barium hydroxide and ammonium chloride reaction are, barium chloride, ammonia and water. Barium chloride is soluble in water and there is precipitation when barium hydroxide iss mixed with ammonium chloride.

Why my teacher said that I should be careful when sodium hydroxide is added to ammonium chloride? Give some reasons.

Sodium hydroxide is corrosive and may damage your skin. The gaseous product, ammonia is a toxic gas and has a potential to kill a human if it is inhaled. So, you should take protective steps to avoid any injuries. You will feel a smell of ammonia when it is released.

What is the reaction when Ba(OH)2 is combined with NH4Cl?

This reaction is an ammonia producing reaction and a weak acid - strong base reaction too.

What happen when barium hydroxide reacts with ammonium chloride?

toxic ammonia gas is emitted.

Is the reaction between barium hydroxide and ammonium chloride exothermic or endothermic?

Reaction is an endothermic one (90.66 kJ).

If Ba(OH) 2+NH4Cl are reactants, then what will be the product?

NH3, BaCl2, H2O
