The salts composed by elements of the first period with halogen elements are a family of compounds with different anionic and cationic combination. In this proposal we aim at measuring the perturbation of the proton zero-point motion in water induced by the presence of ions of different ionic strength. Previous measurements on dilute acid or basic water solutions showed an extended effect of the ions on the surrounding water. Our proposed experiment aims at characterizing the proton quantum state of water in the presence of different high concentrated anions and cations, where the effects of ions is expected to induce large scale perturbations in the neutron Compton profile with respect to the bulk. Quantitative comparison with first principle calculations of the proton kinetic energy will provide the theoretical support of the experiment.
