carbonate CO3^2-
Na^+ is also present. No bicarbonate, due to the excess hydroxide.
H3O^+ and Cl^-
Na^+ and BF4^-

CO2 reacts with water to form H2CO3 (carbonic acid). That will react with sodium hydroxide to form sodium carbonate (Na2CO3). I think you can figure out the ions that sodium carbonate forms.
I'm not sure about the third one...
