ArbitrLikvidat [17]

Answer:

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
