White vitriol is not isomorphous with .

Options

A. `K_(2)SO_(4)`
B. `MgSO_(4)`
C. `CaSO_(4)`
D. `H_(2)SO_(4)`

Explanation

To solve the question "White vitriol is not isomorphous with," we need to understand the concept of isomorphism in chemistry, particularly in the context of crystalline structures.

### Step-by-step Solution:

1. **Define White Vitriol**:
- White vitriol is commonly known as zinc sulfate, which has the chemical formula ZnSO4.

2. **Understanding Isomorphism**:
- Two compounds are said to be isomorphous if they have the same crystal structure, similar unit cell dimensions, and the same space group. They can differ in the types of atoms present, but the overall arrangement and dimensions must be similar.

3. **Identify Compounds to Compare**:
- The question implies we need to compare zinc sulfate (ZnSO4) with other sulfate compounds. Common sulfate compounds include potassium sulfate (K2SO4), magnesium sulfate (MgSO4), calcium sulfate (CaSO4), and sulfuric acid (H2SO4).

4. **Check Crystal Structures**:
- Each of the mentioned compounds has a different crystal structure compared to zinc sulfate:
- **K2SO4**: Potassium sulfate has a different arrangement of ions.
- **MgSO4**: Magnesium sulfate also has a distinct crystal lattice.
- **CaSO4**: Calcium sulfate exhibits a different structure as well.
- **H2SO4**: Sulfuric acid is a molecular compound and does not crystallize in the same manner as the sulfates.

5. **Conclusion**:
- Since all the mentioned compounds (K2SO4, MgSO4, CaSO4, H2SO4) have different crystal structures compared to zinc sulfate, we conclude that white vitriol (ZnSO4) is not isomorphous with any of these compounds.

### Final Answer:
White vitriol (ZnSO4) is not isomorphous with K2SO4, MgSO4, CaSO4, and H2SO4.
