Lissafin pH
Ƙimar pH, pOH, hydrogen-ion da hydroxide-ion taro don sauƙi mai ƙarfi ko monoprotic raunin acid/base bayani.
Ta yaya zan lissafta pH?
Don samfurin acid mai ƙarfi, pH = -log₁₀[H⁺]; don tushe mai ƙarfi, pOH = -log₁₀ [OH⁻] da pH = 14 - pOH a 25 ° C. Rarrauna nau'iKan monoprotic suna magance ma'aunin taro da ma'aunin Ka/Kb, gami da sarrafa Kansa na ruwa. Misali, [H⁺] = 1 × 10⁻ mol/L yana ba da pH 7 a cikin wannan kyakkyawan ƙirar 25 °C.
