# Question bf278

Most carbonates are insoluble, and the quoted solubility of $M g C {O}_{3}$ in water is .......

#### Explanation:

...quoted solubility of $M g C {O}_{3}$ is ....... $0.139 \cdot g \cdot {L}^{-} 1$ at $25$ ""^@C#.

And so we could take a mass of magnesium carbonate, slurry it up in water, and add TWO equiv of hydrochloric acid to give stoichiometric magnesium chloride, as well as carbon dioxide gas, as represented by the given stoichiometric equation:

$M g C {O}_{3} \left(s\right) + 2 H C l \left(a q\right) \rightarrow M g C {l}_{2} \left(a q\right) + C {O}_{2} \left(g\right) + {H}_{2} O \left(l\right)$

All the salt would go up into solution, with bubbling due to the evolved carbon dioxide. So the answer to your question is $\text{YES}$.
