The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Elements**: The question asks about the carbonates of Barium (Ba), Strontium (Sr), and Calcium (Ca). These elements belong to Group 2 of the periodic table, also known as the alkaline earth metals. 2. **Write the Chemical Formulas**: The carbonates of these elements can be represented by their chemical formulas: - Barium Carbonate: BaCO₃ - Strontium Carbonate: SrCO₃ - Calcium Carbonate: CaCO₃ 3. **Determine the Color of the Carbonates**: It is known from chemical literature that the carbonates of these alkaline earth metals are typically white in color. This is a characteristic property of these compounds. 4. **Conclusion**: Since all three carbonates (BaCO₃, SrCO₃, and CaCO₃) are white crystalline solids, the answer to the question is that the carbonates of Ba, Sr, and Ca are white. 5. **Final Answer**: The correct option is A: White. ---
