Bu hasapçy hakda
The pH scale measures how acidic or basic a solution is, defined as the negative base-10 logarithm of the hydrogen-ion concentration: pH = −log₁₀[H⁺], where [H⁺] is in moles per litre. Because it is logarithmic, each whole pH unit is a tenfold change in acidity — a pH 4 solution has ten times the [H⁺] of pH 5 and a hundred times that of pH 6. The scale runs from strongly acidic near 0, through neutral at 7, to strongly basic near 14. This calculator converts a concentration to pH, a pH back to concentration, or starts from pOH.
As a worked example, pure water has [H⁺] = 1 × 10⁻⁷ mol/L, so pH = −log₁₀(10⁻⁷) = 7, which is neutral. A solution with [H⁺] = 10⁻³ mol/L has pH 3 and is acidic; one with pH 11 is strongly basic. The tool also returns pOH and the hydroxide concentration [OH⁻], using the water relationship pH + pOH = 14 at 25 °C — so pH 3 implies pOH 11 and [OH⁻] = 10⁻¹¹ mol/L — and labels the result acidic, neutral or basic.
pH governs a huge range of everyday and industrial processes: the safety of drinking water and swimming pools, soil conditions for gardening, food preservation and brewing, the action of enzymes in the body (blood is tightly held near pH 7.4), and countless chemistry and biology experiments. Note that the 14-point span and the pH + pOH = 14 rule are specific to 25 °C; at other temperatures the neutral point and the sum shift slightly because water’s self-ionisation changes.
Köp soralýan soraglar
pH formulasy näme?
pH, hydrogen-ion concentration's negative base-10 logaritm, pH = −log₁₀[H⁺]. A concentration of 1×10⁻⁷ mol/L gives a neutral pH of 7.
pH we pOH nädip bagly?
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.
pH ölçegi näme?
7'den aşakky ekşi, 7'den aşakky neutral, we 7'den aşakky esasly (alkali)dir. Skala arada 0-14 aralygynda işleýär, emma güýçli ekşi ýa-da esaslar azrak daşyna çykyp biler. Kalkülatör siziň bahaňyzy ekşi, neutral ýa-da esasly diýip sanaýar.
pH näme üçin logaritmikdir?
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 hundred times more than pH 6.
Men pH bahadan [H⁺] nädip tapyp bilerin?
Tersine düşündir: [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.
pH temperatura bilen üýtgeýärmi?
Eý. 7-nji neutral nokat we pH + pOH = 14 düzgüni 25 °C-de saklanar; ýokary temperaturalarda suw has köp ionlaşýar, şonuň üçin neutral pH 7-den aşak düşýär we jemi azrak düşýär. Bu esbap 25 °C standart bahalary ulanýar.
