Magnesium Oxalate
MgC2O4 is most probably named 'magnesium oxalate', though isomers might exist.
Magnesium oxalate (MgC2O4) is generally considered to be insoluble in water. While magnesium salts tend to have varying solubility, magnesium oxalate has a very low solubility product constant (Ksp), indicating that it does not dissolve well in aqueous solutions. Therefore, it will primarily remain as a solid when mixed with water.
The symbol for magnesium in the periodic table is Mg .
The chemical formula of Magnesium IV oxide is: MgO. ****************2nd Opinion ****************** Magnesium doesn't form +4 ions, so I'm thinking the original question was probably about manganese(IV) oxide, which would be MnO2.
No, magnesium oxide is practically insoluble in water; the solubility at room temperature is 0,086 g/L.
