Write electrolyte formulas using the following list of ions: NO3, Mgcl, CO2

Let’s use the solubility table and select soluble compounds that are electrolytes.
NaNO3, KNO3, Ca (NO3) 2, Fe (NO3) 2, Fe (NO3) 3;
MgCl2, MgI2, MgBr2, Mg (NO3) 2, MgSO4;
NaCl, CaCl2, AlCl3, CuCl2, ZnCl2;
CO2 – no anion. Did they mean CO3:
Na2CO3, K2CO3, (NH4) 2CO3.
