[C20: from hydro- + (amm)onium]
hy•dro′ni•um i′on (haɪˈdroʊ ni əm)

proton, forming a hydronium ion
and a hydroxide ion.
Metal sorption starts when the pH rises to the range where most acidic ion exchange sites start to exchange hydronium ion
for metal and the capacity reaches the maximum value in the pH range where all the ion exchange sites take part in the reaction and the functional group is able to form complex with the metal cations (37).
Activated Carbon Surface + Monochloramine + Water [right arrow] Ammonia + Hydronium Ion
+ Chloride Ion + Oxidized Site on the Activated Carbon Surface
It bears repeating that pH is the negative logarithm (base 10) of the hydronium ion
The hydroxide ion also forms more-complicated intermediate structures in water than the hydronium ion
The current output is in effect dependent on the activity of the hydronium ion
in the solution being measured.
