If   a  =      10          −      b      , then by taking the logarithm of both sides, we get  b  =  −      log          10        ⁡  aSince we know the value of   a, you can just substitute.

From   c      [    O          H              −              ]    =      10          −              p        O        H             and   c      [    O          H              −              ]    =  0.003  =  3  ×      10          −      3       we have       10          −              p        O        H              =  3  ×      10          −      3      Hence  −  p      O    H    =  l  o      g          10            3    −  3.So we get  p      O    H    =  3  −  l  o      g          10            3    =  3  −  0.48  =  2.52.
