I want to know the solubility of magnesium on its own, let alone thir compounds.
Mixture of sodium carbonate and magnesium
Magnesium carbonate and sodium sulphate.
MgCI+ NaC ------> MgC + NaCI Magnesium chloride + Sodium carbinate ------> Magnesium carbonate + Sodium chloride.
The precipitate is magnesium carbonate.

sodium hydrogen carbonate, citric acid, sodium chloride, sucrose. Sugar & salt are the best example for solubility
The solubility of sodium carbonate in water at 20 0C is approx. 22 g Na2CO3/100 g water.
MeCO3 where Me is a metal.Ex.: sodium carbonate, potassium carbonate, magnesium carbonate, uranyl carbonate, etc.
That would be D. sodium chloride.
First of all, since Magnesium Carbonate is not Soluble in water you couldn't have a solution of these two salts in water. But if you had a mixture of the two in powdered form and need to separate them simply dissolve what you can in water, the part that wont dissolve is the magnesium carbonate and you could them filter it out and let the solution of sodium carbonate dry out and there you have the two separated.
Examples are: sodium chloride, potassium chloride, calcium chloride, ammonium chloride, ammonium phosphates, sodium carbonate, sodium sulfate, magnesium sulfate, cooper sulfate, magnesium chloride.
Magnesium carbonate is practically insoluble in water; dissolve the salt, filter the solution. Magnesium carbonate remain on the filter, the sodium chloride is now in solution. You can use this solution as table salt solution or by evaporation of the water you can obtain pure crystallized NaCl. But I think that it is more simple to buy pure sodium chloride; also, magnesium carbonate is not dangerous and is a common food additive.
