1. What is pH Calculation for Mixed Solutions?

pH calculation for mixed solutions involves determining the hydrogen ion concentration when two different acidic solutions are combined. The pH is calculated using the weighted average of hydrogen ion concentrations based on their volumes.

2. How Does the Calculator Work?

The calculator uses the pH formula:

\[ pH = -\log(\text{weighted } [H^+]) \]

Where weighted [H⁺] is calculated as: \[ \text{weighted } [H^+] = \frac{(C_1 \times V_1) + (C_2 \times V_2)}{V_1 + V_2} \]

Explanation:

\( C_1, C_2 \) — Hydrogen ion concentrations of solutions 1 and 2 (mol/L)
\( V_1, V_2 \) — Volumes of solutions 1 and 2 (L)
The weighted average accounts for both concentration and volume contributions

3. Importance of pH Calculation

Details: Accurate pH calculation is essential in chemical laboratories, industrial processes, environmental monitoring, and biological systems where precise pH control is critical for reactions and stability.

4. Using the Calculator

Tips: Enter concentrations in mol/L and volumes in liters. Ensure all values are positive and volumes are greater than zero for accurate calculations.
