Question

When bismuth chloride is poured into a large volume of water the white precipitate produced is?
A \[\text{Bi}{{\left( \text{OH} \right)}_{\text{3}}}\]​
B \[\text{B}{{\text{i}}_{\text{2}}}{{\text{O}}_{\text{3}}}\]
C BiOCl
D \[\text{B}{{\text{i}}_{\text{2}}}\text{OC}{{\text{l}}_{\text{3}}}\]

Answer 1

Hint: An inorganic substance with the chemical formula \[BiC{{l}_{3}}\] is known as bismuth chloride. A common source of the \[B{{i}^{3+}}\] ion, it is a covalent molecule. According to VSEPR theory, the species adopts a pyramidal structure both in the gas phase and in the crystal. The synthesis of organic materials uses bismuth chloride as a catalyst. It specifically catalyses the Mukaiyama aldol reaction and the Michael reaction. The catalytic activity is enhanced by the addition of additional metal iodides.

Complete Step by Step Solution:
In the following question, we must identify the result that will be produced when water is introduced to a solution of hydrochloric acid in bismuth chloride.

Let's first learn about bismuth. Butter of bismuth is another name for bismuth chloride, an inorganic covalent molecule. Additionally, bismuth chloride is frequently used as a catalyst in numerous chemical processes.

While bismuth oxychloride, often known as pearl white, is a glossy, white solid. Only from bismuth chloride can bismuth oxychloride be produced.

When water is added to bismuth chloride, it undergoes hydrolysis, which removes one chlorine molecule from the compound and allows oxygen to be added.

Also occurring is the production of hydrochloric acid.
\[BiC{{l}_{3}}~+~{{H}_{2}}O~\to ~BiOCl\text{ }+\text{ }2HCl\]
Here, an oxygen atom is added, which causes the bismuth chloride to oxidise.
By adding hydrochloric acid, the process can be stopped.
Hence option c is correct.

Note: When the bismuth chloride is heated below \[50{}^\circ C\] before the water vapour is introduced. It results in the production of the intermediate monohydrate,\[\text{BiC}{{\text{l}}_{\text{3}}}\text{.}{{\text{H}}_{\text{2}}}\text{O}\]. When ingested by a person, the substance is toxic and lethal because it irritates the digestive system.
