Compound found by hydrolysis of `BiCl_(3)` is:-

Options

A. Bismuth hydroxide
B. Bismuth oxychloride
C. Bismuth oxide
D. Oxo acid of bismuth

Answer

To determine the compound formed by the hydrolysis of BiCl₃ (bismuth trichloride), we can follow these steps:

### Step 1: Understand the Hydrolysis Process
When BiCl₃ is subjected to hydrolysis, it reacts with water. Hydrolysis generally involves the reaction of a compound with water to form a new compound and other products, often resulting in the formation of hydroxides or oxyhalides.

**Hint:** Hydrolysis typically involves the reaction of a compound with water to produce new species.

### Step 2: Identify the Oxidation State of Bismuth
Bismuth can exhibit multiple oxidation states, but in BiCl₃, it is in the +3 oxidation state. This is significant because the +3 state is more stable due to the inert pair effect, which influences the products formed during hydrolysis.

**Hint:** Remember that the oxidation state of the central atom can affect the stability and type of products formed during hydrolysis.

### Step 3: Write the Hydrolysis Reaction
The hydrolysis of BiCl₃ can be represented as:
\[ \text{BiCl}_3 + \text{H}_2\text{O} \rightarrow \text{BiOCl} + \text{HCl} \]

In this reaction, bismuth trichloride reacts with water to form bismuth oxychloride (BiOCl) and hydrochloric acid (HCl).

**Hint:** Look for the formation of oxyhalides when a metal halide undergoes hydrolysis.

### Step 4: Identify the Product
The product formed from the hydrolysis of BiCl₃ is bismuth oxychloride (BiOCl), which is known to be a white precipitate.

**Hint:** Pay attention to the physical state of the product; in this case, it is a white precipitate.

### Conclusion
The compound formed by the hydrolysis of BiCl₃ is bismuth oxychloride (BiOCl).

**Final Answer:** Bismuth oxychloride (BiOCl).
