No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
The pH is the logarithm with changed sign of the ion H+ activity in a solution.
Hydrogen
pH
"pH" is a convention used as a convenience. It indicates how acidic (or basic, that is, alkaline) a solution is. It is the negative logarithm of the hydrogen ion concentration, usually the latter is expressed in moles (or millimoles) per liter. Moles per liter is, of course, what we call "molarity." pOH is used in the same way, indicating the concentration of hydroxyl ions. Generally, Concentration of hydrogen ions + the concentration of hydroxyl ions = 10-14 A neutral solution has equal numbers of H+ and OH-
Acidic
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.
Sodium hydroxide 1 N (normal solution) solution has a concentration of39,99710928 g/L (rounded 40 g/L) or 4 g/100 mL sodium hydroxide in water.
-log(0.13) = 0.88 ----------- 14 - 0.88 = 13.12 1/10(13.12) = 7.59 X 10-14 M hydroxide ion concentration ----------------------------------------------------------
pH of a solution is the negative logarithm of the hydrogen-ion concentration
3: The negative of the logarithm (base 10) of the concentration. The logarithm of 1 is 0 and the logarithm of 10-3 is -3; the logarithm of their product is the sum of their individual logarithms, -3 in this instance, and the negative of -3 is +3.
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.
No. pH is the negative logarithm of the concentration of the hydronium ion. Equal numbers of hydronium ions and hydroxyl ions occurrs only when a solution is neutral.
A common concentration of ammonium hydroxide solution is 25 %.
pH of a substance is directly related to the the amount of H+ ions it produces in the solution. It is the negative logarithm of the concentration of the H+ ions in the solution of a substance.
Neither - its a measure of hydrogen ion concentration.
It depends on the molar concentration (Number of moles per liter of solution, a mole is 6.022X1023 formula units). Since it is a strong base that gives one hydroxide ion per formula unit, the pH of an RbOH solution is equal to 14 + the logarithm of the molar concentration. So a 1.0M solution has a pH of 14, a .1M solution has a pH of 13 and so on until a pH of about 7.

13.7 take the negative logarithm
pOH happens to be the negative log of hydroxide ion' s concentration while pH is the negative log of hydrogen ion's concentration. pH is used to measure the acidity or alkalinity of a solution.
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.
