You do not give a selection of anions.
However, anions with 2- charge are all those of group 6
O2-
S2-
Se2-
Te2-
Po2-
Also the following common acidic anions
Sulphate (SO4^2-)
Carbonate (CO3^2-)
Also in Organic Chemistry The Dioic acids Such as
Ethandioic Acid (Oxalic Acid)
Butandioic Acid (Succinic Acid)
There two acid functional groups in these molecules were the acidic hydrogen can dissociate.
