1. BIFTALATO DE POTASIO 0,050M

Para lograr observar el punto de la interseccin seleccionamos una vista ms adecuada

El punto que se resalta en la grfica corresponde a la interseccin de las grficas donde el pH es 3,35.

3. Titulacin de 25mL cido Tartrico 0,050M con KOH 0,100M

La relacin estequiometria dicta que

y podemos despejar el volumen de equivalencia como

se necesitan para neutralizar un protn del cido.

El volumen de equivalencia es de 12,5 mL KOH ya que el cido es diprtico.

Al adicionar KOH iniciar la neutralizacin del cido hasta antes del punto de equivalencia

Su comportamiento tipo buffer nos permite calcular su pH usando la ecuacin de Henderson-Hasselbalch

Para calcular el pH de la disolucin neutralizada utilizamos el mtodo grfico de la interseccin.

El pH de la disolucin neutralizada est dado por las frmulas:

El pH de equivalencia para la disolucin es 8,52

Luego del punto de equivalencia calculamos pOH segn la frmula:

La grfica que se obtiene de la titulacin de 25,0mL H2Tar 0,05M con KOH 0,100M es la siguiente:

La grafica de la titulacin del cido muestra un punto de equivalencia para el cido.

El rango de viraje del indicador debe ser de cercano a 8, debido a que en este intervalo de pH se alcanza el punto final. El punto de equivalencia es 8,52 por ello cuando adicionamos fenolftalena al sistema, esta cambia su tonalidad a fucsia al pasar el pH 8,3 justo despus del punto de equivalencia.
