WebThe pH is defined as the negative log of the hydrogen ion concentration. At a pH of 7.40, the hydrogen ion concentration is 40 nanoequivalents (nEq) per liter, a very small concentration in comparison to serum sodium at 140 mEq/L. biotin 20000mcg for hair nails skin

WebHydrogen Ion Concentration. If we express the hydrogen ion concentration of an aqueous solution in relation to its molecular value we derive a scale of 1 (10 0) via 10-7 to 10-14 mole/litre. This scale is impractical but if written as a function of its negative logarithm a real and simple scale of 0 –14 has been created: the pH scale. WebpH = −log [H+] The square brackets around the H + automatically mean "concentration" to a chemist. What the equation means is just what we said before: for each 1-unit change in pH, the hydrogen ion concentration changes ten-fold. Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic).
