וואָס איז דער pH־פֿאָרמולע?
pH איז דער נעגאַטיווער לאָגעריטם פֿון די הידראָגען־איאָנעס־צונויפֿשטאַנד, pH = −log₁₀[H⁺]. אַ צונויפֿשטאַנד פֿון 1×10⁻⁷ mol/L גיט אַ ניטראַלן pH פֿון 7.
ווי אַזוי זײַנען pH און pOH פֿאַרבונדן?
At 25 °C, pH + pOH = 14. So a solution of pH 3 has pOH 11, and its hydroxide concentration is [OH⁻] = 10⁻¹¹ mol/L.
וואָס מיינט דער pH-סקעלע?
Below 7 is acidic, exactly 7 is neutral, and above 7 is basic (alkaline). The scale usually runs 0–14, though very strong acids or bases can fall slightly outside it. The calculator classifies your value as acidic, neutral or basic.
װאָס איז pH?
Hydrogen-ion concentrations span many orders of magnitude, so a log scale keeps the numbers manageable. Each unit is a tenfold change: pH 4 is ten times more acidic than pH 5 and a hundred times more than pH 6.
ווי אַזוי געפֿינען איך [H⁺] פֿון אַ pH־באַטרעף?
Invert the definition: [H⁺] = 10^(−pH). A pH of 3 gives [H⁺] = 10⁻³ = 0.001 mol/L. Choose "from a pH value" mode and the calculator returns the concentration for you.
װײַז די רײט
Yes. The neutral point of 7 and the pH + pOH = 14 rule hold at 25 °C; at higher temperatures water ionises more, so neutral pH drops below 7 and the sum falls slightly. This tool uses the standard 25 °C values.
