Each step in pH represents a 10x concentration difference of H+ (protons).
From pH3 --> pH5, there are 2 10x concentration differences of H+. Therefore, there is a x10^-2 difference
Formula is: pH=-log (base 10) [H+]
The H+ concentration of a solution with a pH of 3 is 100 times more concentrated than the H+ concentration of a solution with a pH of 5.
The concentration of H+ is always ten times more than the previous pH. So going from a pH of 6 to a pH of 5, the concentration of H+ is multiplied by 10, and the acid is ten times stronge.
pH = -log[H+] [H+] = 10^(-pH) = 10^(-5) = 0.00005 M for the log of base 10 and M being molarity (mol/L)
pH 4 solution has 10 times more H+ ions as compare to pH 5 solution.
100x greater.
One hundred times.

The value is 100.

A factor of 10 is the difference in a pH of 4 and a pH of 5 regardless of what the solution is.
The pH scale represents a count of ions (hydrogen), or more accurately the "activity" of hydrogen ions. The pH is the negative of the logarithm (base 10) of the concentration in moles per liter. A solution with a pH of 4 is 100 times as concentrated as one with a pH of 6.
You would need to add enough of the alkaline solution to make the total volume 14 litres. The pH of a solution is a measure of the concentration of the hydrogen ion. In fact it is the logarithm of the reciprocal of the hydrogen ion concentration. Water ionizes to give one hydrogen ion per 10 million molecules so the pH is log(10,000,000)=7. The pOH (alkalinity) is obtained by taking the pH away from 14. So pH 8 is equivalent to pOH 6. The pOH is the logarithm of the reciprocal of the hydroxide ion concentration. To achieve neutrality the number of hydrogen ions must balance the number of hydroxide ions. The difference between the pH of the acid solution and the pOH of the alkaline solution is 3. This tells us that the acid is 10 to the power of 3 times i.e. a thousand times more concentrated than the alkaline solution. Thus the acid needs to be diluted to one part in a thousand with the alkaline solution.
1000 times increased. 106-3 = 103 =1000 because the pH scale is logarithmic.
there are more H+ ions in a pH 2 solution that in a pH 4 solution. The hydrogen ion (H+ ion) is responsible for the acidity of a substance and so, the more of it there is, the more acidic it is (higher acidity= lower pH) :)

The pH of a solution measures the hydrogen ion concentration in that solution. A small change in pH represents a large change in hydrogen ion concentration. For example, the hydrogen ion concentration of lemon juice (pH of 2.3) is 63 times greater than that of tomato juice (pH of 4.1), and 50,000 times greater than that of water (pH of 7.0). mustki2005@yahoo.comNigerian
A measure of the concentration of hydrogen ions in solutions is the pH. Solutions with more hydrogen ions are acids, and substances with less hydrogen ions are bases. Furthermore, each number descending has ten times the amount of hydrogen ions of the previous number (ie a solution with a pH of 5 has 1,000 more hydrogen ions than a solution with a pH of 8).
Two of the characteristics of pH are: It is higher for alkalis than for acids. It varies logarithmically with molar hydrogen ion concentration, so that a solution with pH 5 contains ten times as high a molar hydrogen ion concentration as does a solution with pH 6.
The concentration of H+ has increased 10-fold (10X) compared to what it was at pH 9 and the concentration of OH- has decreased to one-tenth (1/10) what it was at pH 9.

3. pH is a negative logarithmic scale. Therefore a difference of 100 times more is translated to -log(100) = -2. Recall the formula pH = -log([H+]).
1000 times increased. 106-3 = 103 =1000 because the pH scale is logarithmic.
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.
A lower pH means more hydronium; each decrease by 1 means the concentration is increased tenfold. You would expect to find fewer hydrogen ions in the pH 6 solution (1000 times fewer ions).
1/103 = 0.001 M ========( pH 3 ) 1/105 = 0.00001 M ============( pH 5 ) As you see, a pH of 3 has a 100 times concentration of 5 pH ( 10 * 10 devalued ) This is the scale; logarithmic.
