Select all ionic compounds in which the number of anions present is two.
carbon dioxide
X manganese(II) hydroxide
mercury(II) carbonate
X mercury(II) phosphate

Hello,
I know manganese(II) hydroxide mercury(II) phosphate both have two anions, however I am unsure about carbon dioxide and sulfur dioxide. would the oxygens in both cases be considered the anion or am I completely off base with this?
Thank you!
