You're looking for acids that contain fluoride (F-) and iodide (I-) anions. Here's the breakdown:

Fluoride Anions (F-)

* Hydrofluoric acid (HF): This is the most common and important acid containing fluoride. It's a weak acid, but extremely corrosive.

* Fluoroboric acid (HBF4): This is a strong acid, but less common than hydrofluoric acid.

Iodide Anions (I-)

* Hydroiodic acid (HI): This is a strong acid. It's a colorless gas that dissolves readily in water.

Important Note: You won't find a single acid that contains both fluoride and iodide anions. These anions have different chemical properties and wouldn't stably coexist in the same compound.
