Summary
| Description |
English: Surface conductivity corresponds to a charge cloud of mobile ions attracted by fixed charges. The moving circle represents the cross section of a negatively charged channel. Its color represents its charge density. Left: At low pH all surface charges are occupied by protons. Surface conductivity vanishes. Right: At high pH all surface charges are available. Surface conductivity becomes a maximum. |
