It is called the litmus test. Sodium Chloride solution is very nearly neutral while Hydrochloric Acid is highly acidic. Blue litmus paper will turn red in the Hcl acid while it will turn rather purple in the neutral NaCl solution. BTW mixing HCL and NaOh ( Sodium Hydroxide) produces a neutral solution of NaCl (Table salt) and H2O (water).
They are totally different things. Nacl is known as Sodium Chloride. It is salt used to prepare dialysate solutions. Hcl is an acid, known as Hydrochloric acid. It is the aqueous solution of hydrogen chloride gas.
You are right they look similar. There are many elements which look similar and only the experiment can tell you the reality. You must be experienced enough to differentiate the basic difference between them.
