Rozsah pH se uzančně udává 0 do 14 (platí pro většinu vodných roztoků při 25 °C, ale teoreticky není tato stupnice omezena, existují například roztoky s pH nižším než 0). Chemicky čistá voda má při pokojové teplotě pH 7 (při 100 °C zhruba 6), kyseliny < 7, zásady > 7. Zobraziť viac pH (anglicky potential of hydrogen, latinsky pondus hydrogenii, či potentia hydrogenii, tj. „potenciál vodíku“), též vodíkový exponent je číslo, kterým se v chemii vyjadřuje, zda vodný roztok reaguje kysele či naopak Zobraziť viac Pro výpočet pH je vždy nutné ujasnit si, co (ne)reaguje s čím.
