uum i think CO3 is trigonal planar, so the 3 O's are arranged equally around the C.

U can tell by the geometry of the molecule. If the molecule is symmetric then it is non polar, if its not semetric, than its polar.
Sulfate (SO_4^2-) has 32 electrons and by the lewis structure, you can see that the molecules electronic geometry is Tetrahedral - Nonpolar because a tetrahedral is Symetrical
Carbonate (CO_3^2-) has 24 electrons and by the lewis stucture the electronic geometry is Trigonal Planar. Non Polar because the Trigonal planar is symetrical

The polarity of the polyatomic ions will depend upon the geometric structure of the ion and the electronegativity of the elements in the ion.
CO3^2- will consist of three oxygen atoms bonded to the central carbon. The shape would be a pyramid with the 3 oxygen atoms forming the base of the pyramid topped by the carbon atom. The C is partially positive while the 3 oxygen atoms are partially negative. It is a polar ion.
The SO4^2- has a tetrahedral shape with the S in the centre and surrounded by 4 O atoms. The central S atom is partially positive and the 4 atoms of O are partially negative. Since the separation of positive and negative charges does not form a dipole, the compound ion is not a problem This is not a polar ion

They are charged -2, but the charges are symmetrically distributed over the O atoms, so the ions themselves are nonpolar.
