Find [H⁺] from pH 7
Kiritish
pH = 7.00
Natija
pH = 7.00, pOH = 7.00, [H⁺] = 1.00 × 10^-7 mol/L, [OH⁻] = 1.00 × 10^-7 mol/L
pH kalkulyatori (pH, pOH va konsentratsiyani aylantirish)
A oddiy pH calculator to aylantirish H⁺, pH, and pOH for education and tezkor field izohlar. It helps you check pH hisoblash, pOH hisoblash, and hydrogen ion konsentratsiya in one place.
See pH / pOH / [H⁺] / [OH⁻] together, with optional formulalar and short amaliy izohlar.
Three kiritish tabs so the starting point is obvious
pH / pOH / [H⁺] / [OH⁻] shown as one fixed set
Formula view, nusxa, and ulashish URL included
Harorat and aktivlik cautions kept visible
Hisoblash assumptions
This vosita performs a asosli aylantirish from konsentratsiya to pH and does not handle aktivlik.
The ion product of suv (pKw) and the neytral point vary with harorat, but this vosita uses the asosli value pKw = 14.00.
Xatolar can become larger for konsentrlangan solutions, buffered systems, or solutions with high ionic strength.
Qanday foydalaniladi
- Choose whether you want to boshlash from pH, [H⁺], or pOH.
- Enter a value to hisoblash pH / pOH / [H⁺] / [OH⁻] immediately.
- Add a harorat izoh if needed, and adjust significant figures for konsentratsiya chiqish.
- Turn on Show formulalar when you want to see the equation and substitution steps.

Atamalar
pH
A logarithmic expression of hydrogen ion konsentratsiya.
pOH
A logarithmic expression of hydroxide ion konsentratsiya.
pKw
The logarithmic form of the ion product of suv. Around 25°C, 14 is often used as the asosli value.
Aktivlik
An effective konsentratsiya term used to describe non-ideal behavior, especially in konsentrlangan or high-ionic-strength systems.
Bufer eritma
A system that resists pH change when kislota or asosiy is added, so it cannot be handled by oddiy pH-to-konsentratsiya aylantirish alone.
Formulalar
pH = -log10([H+])pOH = -log10([OH-])pH + pOH = 14.00[H+] = 10^(-pH)[OH-] = 10^(-pOH)
Tez-tez so'raladigan savollar
Does harorat change the natija?
Strictly speaking, yes. This vosita uses the asosli assumption pKw = 14.00 and treats harorat as a izoh only.
Can I foydalanish this for buffers?
Not directly. Bufer systems need a different model, so a oddiy pH-to-konsentratsiya aylantirish is not enough.
Is this enough for research work?
Treat it as an estimate. For research or sifat nazorat, foydalanish actual measurements, calibration standards, and aktivlik-aware methods when needed.
What birlik does [H⁺] foydalanish here?
This vosita assumes mol/L (M).
Is pH + pOH always 14?
Fourteen is a keng tarqalgan asosli value near 25°C, but pKw changes with harorat. This vosita fixes it at 14.00 for asosli calculations.
Muhim izohlar
- This vosita is intended for education and tezkor field izohlar.
- Actual measurements can differ because of harorat, aktivlik, and ionic strength.
- For research or sifat nazorat, foydalanish a calibrated pH meter and the appropriate corrections for your conditions.
- Do not rely on this asosli hisoblash alone for buffers or highly konsentrlangan systems.
