Solution

1). NaAc (1%) (due to salt of weak acid and strong base)= pH is slightly above 7 (basic pH)

2). NaCl (1%), (due to salt of strong acid and strong base) = pH is 7

3). NH₄Ac (1%) (due to salt of strong acid and weak base) = pH is 7

4). NH₄Cl (1%) (due to salt of strong acid and weak base) = pH is is slightly below 7 (acedic pH)
