Coke on Passover

On Pesach, can Sefardim have American Coca-Cola that is not certified Kasher L’Pesach (The regular Coke)?

Todah in advance.

Many sodas, Coke included, contain citric acid which is commonly derived from wheat and therefore is chametz. When should only purchase soda which is Kosher for pesach.

All the Best
