Title: how do i compute the hydrogen ion content of lemon juice?
Post by: ilndrzrn on Nov 9, 2012
I know the pH is 2.3    I need the hydrogen ion content and how it is computed. Please show work.

[H+]=10^-pH = 10^-2.3 M

This is a very acidic solution!

Every ph unit below 7 is a magnitude of 10 times more H+ to OH- ions. So a ph of 6 would have 10 times more H+ than OH-.  A ph of 5 would have 100 times more H+ than OH-.  Get a linear to logarithmic graph scale.  A ph of 3 would be 10,000 times more H+ than OH-, and a ph of 2 would have 100,000 times more H+.  A ph of 2.3 would have 10 to the 4.7 power, or 50,118.723 times more H+ ions than OH- ions.
