# Is magnesium carbonate soluble in water?

Dec 13, 2015

#### Answer:

Solubility rules holds that all carbonates are insoluble, save for those of the alkali metals. So, the answer is no.

#### Explanation:

As physical scientists we should look at the data. This source quotes the solubility as $0.0106$ $g$ per $100 \cdot m L$ of water. So the stuff is pretty insoluble.

Of course, this presupposes a neutral $p H$. Bicarbonates, salts of $H C {O}_{3}^{-}$ are very soluble.
