pH is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Learn how pH is measured, what it means for different substances and environments, and how it is related to acid dissociation constants and indicators.
pH - Βικιπαίδεια. Η χρήση του pH. Στους 25 °C, η κλίμακα pH κυμαίνεται από 0 έως 14 και χρησιμοποιείται ευρέως για τον προσδιορισμό της οξύτητας ενός διαλύματος. Διαλύματα για τα οποία η τιμή του pH είναι μικρότερη από 7 χαρακτηρίζονται ως όξινα, ενώ διαλύματα με pH μεγαλύτερο από 7 χαρακτηρίζονται αλκαλικά [1].
