When bismuth chloride is poured into a large volume of water the white precipitate produced is

Options

A. `BiO.OH`
B. `Bi_(2)O_(3)`
C. `BiOCl`
D. `Bi(OH)_(3)`

Answer

To solve the question, we need to analyze the reaction that occurs when bismuth chloride (BiCl3) is mixed with a large volume of water. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the compound
Bismuth chloride is represented by the chemical formula BiCl3.

**Hint:** Remember that bismuth chloride is a compound formed from bismuth and chlorine.

### Step 2: Understand the reaction with water
When bismuth chloride is added to a large volume of water, it undergoes hydrolysis. This means it reacts with water to form other compounds.

**Hint:** Hydrolysis reactions often involve the breakdown of a compound in the presence of water, leading to the formation of new substances.

### Step 3: Write the chemical equation
The reaction can be represented by the following chemical equation:
\[ \text{BiCl}_3 + \text{H}_2\text{O} \rightarrow \text{BiOCl} + 2\text{HCl} \]

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

**Hint:** Look for the products formed in a hydrolysis reaction, which often includes an oxy compound and an acid.

### Step 4: Identify the precipitate
The product bismuth oxychloride (BiOCl) is known to be a white precipitate. Therefore, when bismuth chloride is poured into water, the white precipitate produced is BiOCl.

**Hint:** Precipitates are often identified by their color; in this case, we are looking for a white precipitate.

### Conclusion
Thus, the white precipitate produced when bismuth chloride is poured into a large volume of water is bismuth oxychloride (BiOCl).

**Final Answer:** The white precipitate produced is BiOCl.
