What is 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.

PrimeCalcPro provides professional-grade tools trusted by businesses and academics.

ಸೂತ್ರ

▾
f(x)pH = −log₁₀[H⁺] where [H⁺] is the hydrogen ion concentration in mol/L

How to pH Calculator

▾
  1. 1pH = −log₁₀[H⁺] where [H⁺] is the hydrogen ion concentration in mol/L
  2. 2[H⁺] = 10^(−pH)
  3. 3pOH = 14 − pH (at 25°C)
  4. 4Acidic: pH < 7 | Neutral: pH = 7 | Alkaline (basic): pH > 7

Worked Examples

▾
Example 1
Given:[H⁺] = 0.001 mol/L
ಫಲಿತಾಂಶ:pH = 3

−log₁₀(10⁻³) = 3. Acidic (vinegar level)

Example 2
Given:pH = 11
ಫಲಿತಾಂಶ:[H⁺] = 10⁻¹¹ mol/L

Strongly alkaline — bleach, ammonia

Q

What is Ph?

A

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

Q

How accurate is the Ph calculator?

A

The calculator uses the standard published formula for ph. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

Q

What units does the Ph calculator use?

A

This calculator works with inches, Celsius. You can enter values in the units shown — the calculator handles all conversions internally.

Q

What formula does the Ph calculator use?

A

The core formula is: pH = −log₁₀[H⁺] where [H⁺] is the hydrogen ion concentration in mol/L. Each step in the calculation is shown so you can verify the result manually.
