On heating `ZnCl_(2).2H_(2)O`, the compounds obtained is:

Options

A. `ZnCl_(2)`
B. `Zn(OH)Cl`
C. `Zn(OH)_(2)`
D. `Zn `

Answer

To solve the question regarding the compound obtained from heating ZnCl₂·2H₂O, we will follow these steps:

### Step 1: Identify the compound
ZnCl₂·2H₂O is zinc chloride dihydrate. This means that it contains zinc chloride and two molecules of water.

### Step 2: Heating the compound
When ZnCl₂·2H₂O is heated, it undergoes a dehydration reaction. The water molecules (2H₂O) will evaporate, and the zinc chloride will decompose.

### Step 3: Write the decomposition reaction
The heating of ZnCl₂·2H₂O can be represented by the following reaction:
\[ \text{ZnCl}_2 \cdot 2\text{H}_2\text{O} \rightarrow \text{ZnCl}_2 + 2\text{H}_2\text{O} \]
However, upon further heating, zinc chloride can react with any remaining water and hydrochloric acid (HCl) that may be released during the process.

### Step 4: Identify the final products
Upon complete heating, the products that are formed include:
- Zinc chloride (ZnCl₂)
- Zinc chloride hydroxide (ZnOHCl)
- Water (H₂O)
- Hydrogen chloride (HCl)

### Step 5: Conclusion
The main compound obtained from the heating of ZnCl₂·2H₂O is zinc chloride hydroxide (ZnOHCl).

### Final Answer:
The compound obtained on heating ZnCl₂·2H₂O is **ZnOHCl (zinc chloride hydroxide)**.
