aqueous solution - Will this reaction form magnesium carbonate?


I have magnesium oxide pills I take. I know if I dissolve them they'll form magnesium hydroxide, and I'm trying to make pure magnesium from my pills. I've come up with a double replacement reaction, will it do what I think it will?


$$\ce{Na2CO3(aq) + Mg(OH)2(aq) -> MgCO3(s) + 2NaOH(aq)}$$


Will this precipitate out magnesium carbonate?


Another thing: I was planning on using electrolysis to separate the magnesium, but if it's insoluble then I'm not sure what to do. How can I separate the magnesium from the carbonate?

Apparently the of last four, $\ce{Mg^2+}$ is closest in radius to $\ce{Li+}$. Is this true, and if so, why would a whole larger shell ($\ce{...
