What is the pH's typical range?

The human body makes numerous physiological adjustments to maintain homeostasis. One of them is preserving a proper acid-base balance. The pH of a healthy person's body ranges from 7.35 to 7.45, with an average of 7.40, when there are no pathological conditions present.

What is pH's complete form?

What is pH's complete form? "Potential of Hydrogen" is the full name of pH. pH is referred to as the nernst equation of the concentration of H+ ions. So, the definition of pH is "the strength of hydrogen" or "the power of hydrogen."
