Solutions with a higher [H+] than water (pH less than 7) are ,acidic,; solutions with a lower [H+] than water (pH greater than 7) are basic ,or alkaline,. Definition of pH Measuring pH involves comparing the potential of solutions with unknown [H+] to a known reference potential. pH meters convert the voltage ratio between a reference half-cell and a sensing half-cell to pH values.

The cell surface of alkaliphiles has a high concentration of ,acidic, (i.e. negatively charged) molecules and it has been suggested this acts as a “proton sponge”, allowing a more rapid lateral diffusion of protons from the ETS, to the ATP synthase, compared to the rate of diffusion into the surrounding waters [1] Finally, alkaliphiles may use Na + /H + antiport to create a sodium motive force.
