are aqueous solutions of sodium chloride acidic?
In the same way the Cl-ion interacts with the H+ ion of water it forms HCl. Both NaOH and HCl are strong acid and base respectively. The salt NaCl is not HYDROLYSED by water, so this salt Solution will have equal number of H+ ions and OH- ions in Solution. This makes the NaCl Solution neutral with pH=7.
