Los resultados de la tabla son:
a. [OH-]= 1*10⁻⁸
pH= 6
b. [H+]= 2.04*10⁻⁶
[OH-]= 5.34*10⁻¹⁰
c. [H+]= 1*10⁻⁷
[OH-]= 9.61*10⁻⁷
d. [H+]= 2.22*10⁻⁶
pH= 5.65
e. [H+]= 1.55*10⁻⁷
[OH-]= 1.54*10⁻⁷
Explicación:
Para la resolución de la tabla se tienen en cuenta las siguientes fórmulas:
a. [OH-]= Kw/ [H+]
[OH-]=1*10⁻¹⁴/ 1*10⁻⁶ =1*10⁻⁸
pH= -log (1*10⁻⁶)=6
b.
=2.04*10⁻⁶
[OH-]= Kw/ [H+]
[OH-]=1.13*10⁻¹⁵/ 2.04*10⁻⁶ =5.34*10⁻¹⁰
c.
=1*10⁻⁷
[OH-]=9.61*10⁻¹⁴/ 1*10⁻⁷ =9.61*10⁻⁷
d. [H+]= Kw/ [OH-]
[H+]=1*10⁻¹⁴/ 4.5*10⁻⁹ =2.22*10⁻⁶
pH= -log (2.22*10⁻⁶)=5.65
e.
=1.55*10⁻⁷
[OH-]=2.38*10⁻¹⁴/ 1.55*10⁻⁷ =1.54*10⁻⁷
