Change in pH Calculator





Formula

The following formula is used to calculate the change in pH:

\[ \Delta pH = pH_f - pH_i \]

Definition

To calculate the change in pH, subtract the initial pH (pHi) from the final pH (pHf). This will give you the difference in pH levels.

Example Calculation

Let's say we have an initial pH of 5.5 and a final pH of 7.2. To find the change in pH, we can use the formula:

\[ \Delta pH = 7.2 - 5.5 = 1.7 \]

Therefore, the change in pH is 1.7.
