Answer:
ph = 4.73
Explanation:
Determine the pH of a 0.62 M NH4NO3 solution at 25C
The Kb for NH3 is 1.76 x 10^-5
NH4+ is the conjugate acid of the base NH3
Ka for NH4+ = K water / K NH3 conjugate base
Ka = 1 × 10⁻¹⁴ / 1.76 10⁻⁵
= 5.68 × 10⁻¹⁰
which is he Ka for
NH4 + H2O --> NH4OH + H⁺
Ka = [NH4OH] [H+] / [NH4)+]
5.68 × 10⁻¹⁰ = [X] [X] / [0.62]
X² = 3.52 × 10⁻¹⁰
X = [H+] = 1.88 × 10⁻⁵
p of that H+ = 4.73
ph = 4.73
