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).

This is because protons in water as hydronium ions have an anomalous 12-times faster diffusion than their diameter predicts (Kunkel et al.
The research question regarded the structural and material change of contact lenses in various concentrations of hydronium or hydroxide ions in solution (measured by pH).
A low pH indicates a high concentration of hydronium ions, while a high pH indicates a low concentration.
The columns used were: (1) Cation trap column CS12A high efficiency cation-exchange resin in the hydronium form, (4 x 250 mm) analytical.
Hydrogen sulphide also reacts with water molecules to form hydronium, again a highly- acidic substance," Sudhir Khera, an engineer, said.
When the positively charged droplets come into contact with the sample being tested, the hydronium ions transfer their extra proton to molecules in the sample, turning them into ions.
