Question

what is the formula of the compound given below? hydrofluoric acid hfi (aq) hf (aq) hfo (aq)

Explanation:

Hydrofluoric acid is a binary acid composed of hydrogen and fluorine. The chemical symbol for hydrogen is H and for fluorine is F. In the aqueous form (aq), the formula is HF (aq). HFI is incorrect as I is the symbol for iodine, not relevant here. HFO would imply the presence of oxygen which is not in hydrofluoric acid.

Answer:

B. HF (aq)
