pH is the negative log of the hydrogen ion concentration. So lowering pH from 5 to 4 means a ten times increase in hydrogen ion concentration. Increasing pH by 1 results in decreasing hydrogen ion concentration to 1/10th its former level.

How is the pH scale shifted by the use of hydrogens ions?
pH is a measure of Hydrogen concentration pH = -log10[H+], where [H+] is the concentration of hydrogen ions. From this equation, we can see that an increase of hydrogen ions will lower the pH, and a decrease of hydrogen ions will raise the pH. =D
What scale measures the concentration of hydrogen ions?
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
Does a pH of 3 have a greater hydrogen ion concentration than a 9 pH?
pH come from "pondus hydrogenii" or "potential hydrogen." It measures the concentration of hydrogen ions. Mathematically, pH = -log[H+] Therefore, to answer your question, a pH of 3 will have a 10-3M of hydrogen ions where as the pH 9 solution will have a 10-9M of hydrogen ions. The lower the pH the higher its H+ concentration and the more acidic it is. (A pH of 9 is actually basic.)
Is it true that The pH scale measures the concentration of hydroxide ions?
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.
The measurement of the concentration of hydrogen ions in a solution is called?
Potential of hydrogen or PH

Does the pH scale indicate the consentration of hydrogen ions or hydroxide ions?
pH stands for power of hydrogen and indicates concentration of Hydrogen ions. pOH indicates concentration of hydroxide ions.
What is the concentration of hydrogen ions commonly expressed as?
The concentration of hydrogen ions is commonly expressed as pH.
Concentration of hydrogen ions in solution is called?
Concentration of hydrogen ions in a solution is called: Acid concentration and pH = - log10(hydrogen ions concentration, in mol/l)
What can measure pH?
The concentration of hydrogen ions
Why you need pH?
pH is used as a measurement of the concentration of hydrogen ions in a solution. pH is the negative logarithm of the hydrogen ion concentration.
What scale measures the concentration of hydrogen ions?
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)
How is the pH determined?
By the concentration of hydrogen and/or hydroxide ions. For example, water (H2O) has an equal concentration of hydrogen and hydroxide ions. Hence, it is neutral (pH 7).
How is the concentration of hydrogen ions and hydroxide ions related in aqueous solutions?
Hydrogen ions: pH under 7.Hydroxide ions: pH over 7.
What is the PH of a solution in which the concentration of hydroxide ions is greater than the concentration of hydrogen ions?
< 7
