Concepts and reason
This problem is based on the concept of Nuclear magnetic resonance which involves the absorption of radiations in the radio frequency region. This spectroscopy is generally used for the determination of the type and number of protons present in a molecule.
Fundamentals
A spinning charge creates a magnetic field and therefore behaves as a tiny magnet . The spinning nuclei generate a magnetic field on exposure to an external magnetic field . If an external magnetic field is applied , spinning nuclei can get oriented in two ways:
The magnetic field due to nuclei is in the same direction as the external field. In this case, the nuclei are said to be in a low energy spin state.
The magnetic field due to nuclei is in the opposite direction as the external magnetic field. In this case, the nuclei are said to be in high -energy spin state.

Answer:
Explanation:
HF ,Hydrofluoric acid happens to be a weak acid and as we know that a weak acid is partially dissociated in water.
So when we dissolve HF in water it would subsequently dissociate into H⁺ and F⁻ions . The solution now would contain hydronium ion that is H+ ion.
The solution would also contain dissociated F⁻ ion and solvent H20 molecules.
The following reaction would take place:
HF+H₂O⇆H₃O⁺+F⁻
so the reaction in forward direction is the dissociation of HF into H₃O⁺(that is H⁺) and F⁻ion.
The backward reaction would be the recombination of H₃O⁺(that is H⁺) and F⁻ion to give back HF and H₂O
