Using a logarithmic function, it is found that the concentration of hydrogen ions of a solution whose ph is 7.2 is of [tex]H = 6.31 \times 10^{-8}[/tex].
The function is given by:
[tex]pH = -\log{H}[/tex]
In this problem, we have that pH = 7.2, and we want to solve to find H, hence:
[tex]pH = -\log{H}[/tex]
[tex]\log{H} = -pH[/tex]
[tex]\log{H} = -7.2[/tex]
[tex]10^{\log{H}} = 10^{-7.2}[/tex]
[tex]H = 6.31 \times 10^{-8}[/tex]
