This will depend on the concentration.
However NH4+ ions are weakly acidic (pKa = 9.25) so the pH value of an 1.0 M NH4+solution will be about 4.6
Nitrate ions are neutral.

The pH of a solution of NH4NO3, which is a salt formed from ammonium and nitrate ions, is typically around 5.5-6.5. This is because NH4NO3 can undergo hydrolysis in water, leading to the formation of acidic ammonium ions (NH4+) and basic nitrate ions (NO3-).
When ammonium nitrate (NH4NO3) dissolves in water, it dissociates into ammonium ions (NH4+) and nitrate ions (NO3-). This process is endothermic, meaning it absorbs heat from its surroundings. The dissolution of NH4NO3 also results in a decrease in pH due to the release of hydrogen ions (H+).
NH4NO3 dissociates in water to form NH4+ and NO3-, resulting in a slightly acidic solution due to the presence of NH4+ ions, which can hydrolyze to form H3O+.
The molecular formula for ammonium nitrate is NH4NO3.
The reaction between water and ammonium nitrate (NH4NO3) forms ammonium nitrate solution. The equation is: NH4NO3 (s) + H2O (l) → NH4NO3 (aq).
NH4NO2 has a higher pH than NH4CN. NH4NO2 is the salt of a weak acid (nitrous acid) and a strong base (ammonia), resulting in a basic pH. NH4CN is the salt of a weak acid (hydrocyanic acid) and a weak base (ammonia), resulting in a slightly acidic pH.
