WebSep 17, 2014 · Die pH-Skala misst, wie sauer oder basisch eine Substanz ist. Sie reicht von 0 bis 14. Der pH-Wert von destilliertem Wasser beträgt 7 und wird als neutral bezeichnet. Ein pH-Wert unter 7 ist sauer und ein pH-Wert über 7 ist basisch. http://www.starch.dk/isi/tables/monographs/PhEUR%20Methods.pdf
The pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH value representing a tenfold difference in hydrogen ion concentration.
