    NH4Cl, NaCl, Ba (OH) 2, NaOH

    Explanation:

    NH4Cl is an acidic salt formed by the neutralization of a strong acid (HCl) with a weak base (NH3). Hence, it will habe a PH<7 (the lowest PH).

    NaCl is a neutral salt, formed by neutralization of a strong acid (HCl) with a strong base (NaOH). Hence, it will have a PH of 7.

    Ba (OH) 2 is a weak base. Therefore, it will have a PH between 8 and 10.

    NaOh meanwhile, is a strong base. Therefore, it will have a PH between 10 to 13.

    Hence, we have

    NH4Cl < NaCl < Ba (OH) 2 < NaOH
