Explanation: i took the tet
Either covalent or ionic... they are nonmetals meaning that the are a component in both types of compounds
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻
c=9,50*10⁻² mol/L
Ammonia solution is a weak electrolyte.
The dissociation constant of ammonium hydroxide is:
K=1.78*10⁻⁵
[OH⁻]=√(Kc)
pH=14-pOH=14+lg[OH]⁻
pH=14+lg(√(Kc))
pH=14+lg(√(1.78*10⁻⁵*9.50*10⁻²))=8.23
pH=8.23
