Uma solução aquosa de cloreto de amônio 0,2 mol/L apresenta um grau de hidrólise igual a 0,5%. Determine a [H+], [OH –], pH, pOH e Kh para essa solução e o Kb para o NH4OH.
Dado: Kw = 10– 14, a 25°C.
NH4+ + H2O ⇌ NH4OH + H+

An aqueous solution of 0.2 mol / L ammonium chloride contains a degree of hydrolysis equal to 0.5%. Determine [H +], [OH -], pH, pOH and Kh for that solution and or Kb for NH4OH.
Given: Kw = 10–14, at 25 ° C.
NH4 + + H2O ⇌ NH4OH + H +
