AI Generated Solution

The correct Answer is:
To determine the color of hydrated zinc sulfate, we can follow these steps: ### Step 1: Identify the chemical formula of zinc sulfate. - The chemical formula for zinc sulfate is ZnSO₄. ### Step 2: Understand the hydrated form of zinc sulfate. - The hydrated form of zinc sulfate is represented as ZnSO₄·7H₂O. The "7H₂O" indicates that there are seven molecules of water of crystallization associated with each formula unit of zinc sulfate. ### Step 3: Determine the color of hydrated zinc sulfate. - Hydrated zinc sulfate (ZnSO₄·7H₂O) is known to be a white crystalline solid. ### Step 4: Consider the anhydrous form of zinc sulfate. - When heated, hydrated zinc sulfate loses its water of crystallization and converts to anhydrous zinc sulfate (ZnSO₄). The anhydrous form is also white in color. ### Step 5: Conclude the color of hydrated zinc sulfate. - Therefore, the color of hydrated zinc sulfate is white. It is also commonly referred to as "white vitriol." ### Final Answer: The color of hydrated zinc sulfate is white. ---
