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 ... curl-ups benefitsDa Redoxpotentiale von äußeren Bedingungen wie Druck, Temperatur oder dem pH-Wert abhängig sind, wurde zur besseren Vergleichbarkeit ein Standardzustand definiert, in dem sich die in der Elektrochemischen Spannungsreihe stehenden Halbelemente befinden.
