Kaip apskaičiuoti Ph Calculator

Kas yra Ph Calculator?

pH is a logarithmic scale measuring the acidity or alkalinity of a solution, ranging from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral (pure water at 25°C). Each unit represents a 10× change in hydrogen ion concentration.

Formulė

pH = −log₁₀[H⁺] where [H⁺] is the hydrogen ion concentration in mol/L
H
10^(−pH) — 10^(−pH)
L
L value — Variable used in the calculation

  4. 4Acidic: pH < 7 | Neutral: pH = 7 | Alkaline (basic): pH > 7

Worked Examples

Įvestis
[H⁺] = 0.001 mol/L
Rezultatas
pH = 3
−log₁₀(10⁻³) = 3. Acidic (vinegar level)
Įvestis
pH = 11
Rezultatas
[H⁺] = 10⁻¹¹ mol/L
Strongly alkaline — bleach, ammonia

Frequently Asked Questions

What is Ph?

pH is a logarithmic scale measuring the acidity or alkalinity of a solution, ranging from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral (pure water at 25°C). Each unit represents a 10× change in hydrogen ion concentration

How accurate is the Ph calculator?
