Question

Are Metal Carbonates Soluble In Water?

Answer 1

1. All carbonates are insoluble except those of sodium, potassium, and ammonium.
2. Magnesium carbonate is slightly soluble.
3. Many hydrogen carbonates, such as $\mathrm{Ca}{\left({\mathrm{HCO}}_3\right)}_2$ and $Mg{\left(HC{O}_3\right)}_2$ are soluble.
4. So, all metal carbonate is not soluble in water.
