Titratable Acidity Calculation Using pH Meter
Titratable acidity is a crucial parameter in various industries, including food, beverages, and pharmaceuticals. Accurately measuring it using a pH meter ensures product quality and consistency. Our calculator simplifies this process.
How to Use This Calculator
- Select the acid from the dropdown.
- Enter the volume and concentration of the acid.
- Click ‘Calculate’.
Formula & Methodology
The calculation is based on the Henderson-Hasselbalch equation and the volume of acid added. The formula is:
TA = (V * C * MW) / (1000 * Vt)
Where TA is titratable acidity, V is volume, C is concentration, MW is molecular weight, and Vt is total volume.
