Galvanic cell
Spontaneous reaction at electrodes
How do pH meters work?
Higher conc of H+ in the analyte and therefore the hydrated glass causes Na+ ions to diffuse across the glass and push H+ ions from the hydrated glass into the buffer - increasing the activity of the buffer and causing a lower pH
Example of a pH electrode
Ag (s) |AgCl (s) | KCl (aq) || analyte | glass | buffer | NaCl (aq) | AgCl (s) | Ag (s)

Helmholtz layer model
Surface charge compensated by a fixed sheet of ions at the outer helmholtz layer
Gouy-Chapman model
Surface charge counterbalanced by a dynamic ionic atmosphere - diffuse layer
