Ph the power of hydrogen
WebThe pH is defined as the logarithm of the inverse of the hydrogen ion activity. It’s called Hydrogen ion POTENTIAL. It was defined for aqueous solutions. In pure water, hydrogen ion activity is 10^-7, therefore, the pH, as defined, is 7. The meaning of POTENTIAL is the hability to produce something, or in the specific case of pH, absorb something.

The negative log of the hydrogen ion … WebThe letters pH stand for the power of the hydrogen ion. The pH of a solution is the negative logarithm of the hydrogen-ion concentration. pH = -log [H + ] In pure water or a neutral solution the [H + ] = 1.0 × 10 -7 M. Substituting into the pH expression: pH = -log [1.0 × 10 -7 ] = - (-7.00) = 7.00
WebJan 18, 2024 · The full form of pH is the “power of Hydrogen”. The concept of pH was proposed by Soren Sorensen, a Danish chemist. It is an equation that shows even the smallest amount of H+ ions in a solution. pH is the negative of the base-ten logarithm of the concentration of H + or H 3 O + expressed in moles/liters. pH scale has values ranging …
