WebFeb 24, 2024 · Der pH-Wert wirkt sich außerdem auf die Wasserlöslichkeit einiger Schadstoffe aus. Die Trinkwassergrenzen für den pH-Wert liegen im Bereich pH >6,5 bis pH <9,5. Das Redoxpotential E h beschreibt das Konzentrationsverhältnis von oxidierten und reduzierten Stoffen und somit die elektrochemischen Bedingungen im Wasser. Die … WebApr 18, 2003 · Let us now consider some examples of enzymatic redox reactions with the pH-dependent redox potential. An interesting case presents the Rieske protein whose redox potential varies due to, most probably, protonation–deprotonation of a His liganding the Fe 2 S 2 cluster [5], [6]. Corresponding pK o =7.6 and pK r ∼10.

WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion concentration. The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although ...
