1. As Potassium chloride salt is produced by strong acid HCl and strong base like KOH. so it is neutral salt. Its PH value is 7.
2. sodium Carbonate is a basic salt so its PH value is greater than 7
3. Ammonium suplhate is a acidic salt formed by Weak base NH3 and strong acid H2SO4.So its PH Value is > 7.
4. sodium nitrate is neutral salt hence its Ph is equal to 7.
