Dès le dix-septième siècle, Robert Boyle utilise des décoctions de plantes comme indicateurs colorés. Dans son ouvrage «expériences sur les couleurs» il explique en 1663 comment mettre en évidence le caractère acide des solutions à l'aide de sirop de violette. 1, record 1, French, - indicateur%20color%C3%A9%20acido%2Dbasique

A common measure of acidity is pH, which is defined as the negative logarithm of the hydrogen-ion concentration. The pH scale ranges from 0 to 14, with a value of 7 representing a solution that is neutral, values below 7 indicating greater acidity and values above 7 indicating greater alkalinity. 2, record 2, English, - pH%20scale
Record number: 2, Textual support number: 2 CONT
... the pH scale is a logarithmic scale; a substance with a pH of 4 is more than twice as acid as a substance with a pH of 5. Similarly, a substance with a pH of 9 is much more than twice as alkaline as a substance with a pH of 8. 3, record 2, English, - pH%20scale
