1. What is the pH Mixing Equation?

The pH mixing equation calculates the resulting pH when two aqueous solutions are combined. It accounts for the hydrogen ion concentration of each solution and their respective volumes to determine the final pH of the mixture.

2. How Does the Calculator Work?

The calculator uses the pH mixing equation:

\[ pH_{mix} = -\log\left(\frac{10^{-pH_1} \times V_1 + 10^{-pH_2} \times V_2}{V_1 + V_2}\right) \]

Where:

\( pH_1 \) — pH of first solution
\( V_1 \) — Volume of first solution (L)
\( pH_2 \) — pH of second solution
\( V_2 \) — Volume of second solution (L)

Explanation: The equation converts pH values to hydrogen ion concentrations, calculates the weighted average based on volume, then converts back to pH scale.

3. Importance of pH Calculation

Details: Accurate pH calculation is crucial for chemical reactions, biological systems, water treatment, and many industrial processes where pH control is essential.

4. Using the Calculator

Tips: Enter pH values between 0-14 and positive volume values. The calculator assumes ideal solutions and no buffering effects or chemical reactions between components.

5. Frequently Asked Questions (FAQ)

Q1: Does this work for buffered solutions?
A: No, this equation is for non-buffered solutions. Buffered solutions require more complex calculations accounting for buffer capacity.

Q2: What if the solutions react with each other?
A: This calculator assumes no chemical reaction between solutions. If reactions occur, additional calculations are needed.

Q3: Can I mix more than two solutions?
A: Yes, the equation can be extended: pH_mix = -log(Σ(10^{-pH_i} × V_i)/ΣV_i)

Q4: What temperature is this valid for?
A: The calculation is temperature-independent as it uses pH values which already account for temperature effects.

Q5: How accurate is this calculation?
A: It's mathematically exact for ideal solutions, but real-world factors like ionic strength may cause slight deviations.
