What is diffusion?
This directional term describes a structure closer to the body surface.
What is superficial?
A substance that shifts the H⁺/OH⁻ balance in favor of hydrogen ions.
What is an acid?
This ion increases in concentration when a solution becomes more acidic.
What is the hydrogen ion (H⁺)?
