Kuinka laskea pH

Mikä on pH?

pH is the negative base-10 logarithm of hydrogen ion concentration [H⁺]. This calculator converts between [H⁺] (mol/L) and pH — the fundamental measure of acidity.

Kaava

pH = −log₁₀[H⁺] | [H⁺] = 10^(−pH)

[H⁺]: Hydrogen ion concentration (mol/L)
pH: Power of hydrogen (dimensionless)
pOH: Power of hydroxide (dimensionless)

Vaiheittainen opas

1pH = −log₁₀([H⁺])
2[H⁺] = 10^(−pH)
3pH < 7: acidic; pH 7: neutral; pH > 7: alkaline
4Each pH unit = 10× change in [H⁺]

Ratkaistut esimerkit

Syöte

[H⁺] = 0.001 mol/L

Tulos

pH = −log(0.001) = 3 (acidic)

Syöte

pH = 11

Tulos

[H⁺] = 10⁻¹¹ mol/L (strongly basic)
