pH to Ion Concentration Equation:
From: | To: |
The pH to ion concentration calculation converts the pH scale value to the actual hydrogen ion concentration in a solution. This is fundamental in chemistry, biology, and environmental science.
The calculator uses the following equation:
Where:
Explanation: The pH scale is logarithmic, meaning each whole pH value below 7 is ten times more acidic than the next higher value.
Details: Knowing the exact hydrogen ion concentration is crucial for chemical reactions, biological processes, water treatment, and many industrial applications.
Tips: Enter a pH value between 0 and 14. The calculator will compute the corresponding hydrogen ion concentration in moles per liter (mol/L).
Q1: What is the relationship between pH and ion concentration?
A: pH is the negative logarithm (base 10) of the hydrogen ion concentration. A lower pH means higher hydrogen ion concentration.
Q2: What is the ion concentration at pH 7?
A: At pH 7 (neutral), the hydrogen ion concentration is exactly 1 × 10⁻⁷ mol/L.
Q3: How precise is this calculation?
A: The calculation is mathematically exact, but real-world measurements may have experimental error.
Q4: Can this be used for very high or low pH values?
A: The calculation works theoretically for any pH, but extreme values may not be physically meaningful in most applications.
Q5: Why is the concentration in mol/L?
A: Molarity (mol/L) is the standard unit for concentration in chemistry, representing moles of solute per liter of solution.
