Which of the following is the correct chemical formula for hydrofluoric acid?
A
HF2
B
HF
C
HCl
D
H2F
Verified step by step guidance1
Understand that hydrofluoric acid is an acid formed by hydrogen and fluorine.
Recall that the chemical formula for hydrofluoric acid consists of one hydrogen atom and one fluorine atom bonded together.
Recognize that the correct formula should reflect the simplest ratio of hydrogen to fluorine, which is 1:1.
Evaluate the given options: HF2 suggests two fluorine atoms, which is incorrect; HCl is hydrochloric acid, not hydrofluoric acid; H2F suggests two hydrogens and one fluorine, which is incorrect.
Conclude that the correct chemical formula for hydrofluoric acid is HF.
