I-Calculator ye-pH
Guqula phakathi kwe [H⁺], pH, pOH ne [OH⁻] futhi uhlukanise ukusabela.
Iziphetho zivuselelwa uma ubhala.

Imibuzo ebuzwa kaningi
Yini ifomu le-pH?
I-pH iyi-logarithm engekho esiteji-10 ye-hydrogen-ion concentration, i-pH = −log₁₀[H⁺]. I-concentration ye-1×10⁻⁷ mol/L inikeza i-pH engaguquki engu-7.
Uyini ukuxhumana phakathi kwe-pH ne-pOH?
Ku-25 °C, i-pH + pOH = 14. Ngakho-ke, isixazululo se-pH 3 sine-pOH 11, futhi ukuthambekela kwayo kwe-hydroxide ku- [OH⁻] = 10⁻¹¹ mol/L.
Iyini inkinga ye pH?
Izinga livame ukudlula ku-0-14, kepha ama-asidi anamandla noma ama-bases angawela kancane ngaphandle. I-calculator ihlukanise inani lakho libe yi-asidi, i-neutral noma i-base.
Kungani i-pH ilingana?
I-hydrogen-ion concentrations ihlanganisa izimiso eziningi ze-magnitude, ngakho-ke i-log scale igcina inani lilawulwa. Iyunithi ngayinye ishintsha ngezikhathi ezingu-10: i-pH 4 i-acid kakhulu kune-pH 5 futhi i-pH 6 ingaphezu kwe-pH 100.
Ngiyithola kanjani i-[H⁺] kusuka ku-pH?
Buyisela umqondo: [H⁺] = 10^(−pH). I-pH engu-3 inikeza [H⁺] = 10⁻³ = 0.001 mol/L. Khetha "ukusuka ku-pH value" mode futhi i-calculator izobuyisela ukucindezeleka kuwe.
Ingabe i-pH ishintsha ngokushisa?
Yebo. Ingxenye engenalutho ye-7 ne-pH + pOH = 14 imithetho igcina ku-25 °C; ezindaweni eziphakeme amanzi athola i-ionization, ngakho i-pH engenalutho iwela ngaphansi kwe-7 futhi i-sum iwela kancane. Lezi zisetshenziswa zisebenzisa ama-values ajwayelekile we-25 °C.
