The pH of saliva typically ranges from 6.2 to 7.6, corresponding to an H+ concentration of around 10^-6 to 10^-8 moles per liter.
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
Concentration. It will generally flow from an area of high concentration to an area of low concentration.
pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that. Similarly, one can find the pOH simply by substituting the concentration of OH- for the concentration of H+ in the aforementioned formula.
H plus ion concentration can be decreased by adding base to the solution. The reduction can also be done by accepting hydrogen ions.
Hydrogen ion (H+) [technically it is hydronium ion (H3O+)] that determines the strength of an acid. A mole of hydrochloric acid (HCl) produces 1 mole of H+ ions, then that is a strong acid. Weak acids give smaller amounts of H+ for a mole of substance.
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
H plus ions would not flow
High concentration of H+ ion in the intermembrane lead to the movement of H+ ions into the inner membrane
When the pH drops from 7 to 5 the H plus concentration increases by 100 times. ie:for every drop back of pH by 1 unit the H plus concentration increases by 10 times.
Vinegar is an acid. But it is weak
Concentration. It will generally flow from an area of high concentration to an area of low concentration.
Adding hydrochloric acid to water would increase the concentration of H+ ions, leading to a decrease in pH. Hydrochloric acid dissociates in water to form more H+ ions, making the solution more acidic.
When pH value is decreased 1.0 unit, the H+ concentration is tenfolded, because -log(10.[H+]) = pH + 1.0
It increases.

Yes, the pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. pH is defined as the negative logarithm of the hydrogen ion concentration.
