Der pH-Wert (Abkürzung für Potential des Wasserstoffs, lat. pondus hydrogenii oder potentia hydrogenii) ist ein Maß für den sauren oder basischen Charakter einer wässrigen Lösung. Er ist die Gegenzahl des dekadischen Logarithmus (Zehnerlogarithmus) der Wasserstoffionen-Aktivität und eine Größe der Dimension Zahl. Je höher die Konzentration der Wasserstoffionen in der Lösun… WebMar 17, 2014 · The pH of 0.1 M sodium acetate is calculated as follows: K_b = 5.56x10^(-10) = ([OH^-][HA])/([A^-]) = x^2/(0.1-x) ≈ x^2/0.1 x = (0.1 K_b)^(1/2) = 7.46x10^(-6) = …
WebMar 16, 2024 · The pH to H+ formula that represents this relation is: \small \rm {pH = -\log ( [H^+])} pH = −log( [H+]) The solution is acidic if its pH is less than 7. If the pH is higher, the … 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).

WebJan 18, 2024 · Most solutions have a pH value between 0 and 14 on the pH scale. Solutions with a pH value of 7, at the middle of the pH scale, are called neutral. If a solution has a pH value smaller than 7, it’s called acidic. If the pH value is larger than 7, the solution is called basic or alkaline.
WebApr 2, 2024 · The blood pH in the range of 7.45 to 7.35 is considered healthy, but outside of this range causes medical problems.
