Which one of the alkaline earth metal carbonates is thermally the most stable?A. `MgCO_(3)`B. `CaCO_(3)`C. `SrCO_(3)`D. `BaCO_(3)` |
| Answer» d. As the electropositive character of the metal increases or the basicity of their hydroxides increases down the group, their thermal stability increases. Thus, `BaCO_(3)` is the most stable and hence option (d) is correct. | |
