No, because NaCl is a neutral salt and doesn't affect the pH. Obviously such a high salt concentration change the chemical activity of the ions so the acid-base equilibrium will change. Even if you had added a strong acid would you see the effect of salt as pH is defined as the log to the activity of H+.
