 ```The solubility of magnesium carbonate, MgCO3, in aqueous solution at 25oC is 4.5 x 10^-3 mol L-1. The solubility product, Ksp, of MgCO3 at 25oC is? Please show workings on how you acheived the answer. Cheers :)``` There is no answer at this time. Subject: Re: Chemistry - Solubility Products Ksp From: dr_morph-ga on 10 Oct 2006 19:40 PDT
 ```Magnesium carbonate MgCO3 6.82×10-6 http://www.ktf-split.hr/periodni/en/abc/kpt.html```

 ```p.s. I think that since the Ksp is 6.82*10^-6, therefore the solubility is the square root of 6.82*10-6, since Ksp=[Mg][CO3]. Therefore the solubility is not 4.5 x 10^-3, but is actually 2.6 x 10^-3```

 ```however, assuming you are correct, and paying for this ;), if the solubility is 4.5 x 10^-3, therefore [mg]=4.5 x 10^-3 and [CO3]=4.5 x 10^-3, and Ksp=[Mg][CO3]Ksp=(4.5 x 10^-3)^2 = 2.025 X 10^-5```

 `The second answer is correct thanks for your time and effort :)`
