Calculo de pH en disoluciones acuosas

A partir de los datos que se indican calcula el pH de las siguientes soluciones acuosas, así como el tipo de disolución de acuerdo con el pH que determines.

1. Disolución A {H+}= 1x 10-5 M

          Formula                                              Sustitucion                                                Tipo de disolución
          pH = _log {H+}                                 pH = _log {1x10-5}                                 ácida
                                                                     pH =5

     2.  Disolución B{OH-}= 2.25 x 10-3 M

          Formula                                              Sustitucion                                                Tipo de disolución
          pOH = _ log {OH-}                            pOH = -log {2.55 x 10-3}                       básica
                                                                      pOH = 2.6
   3. Disolución C si {OH} = 300 Kw


          Formula                                              Sustitucion                                                Tipo de disolución
          
          pOH = _ log {OH-}                             pOH = -log {300 Kw}                            ácida
                                                                       pOH = -log {300(1x10-14)}
                                                                       pOH =  11.52
Aplicando: pH+ pOH = 14                                                                         Despejando: pH =14 - pOH
                                                                                                                                       pH= 14 - 11.52
                                                                                                                                       pH = 2.48
