1. What is pH of Mixed Solutions?

The pH of mixed solutions calculates the resulting pH when two acidic or basic solutions are combined. It considers the volumes and concentrations of both solutions to determine the new hydrogen ion concentration.

2. How Does the Calculator Work?

The calculator uses the pH mixing equation:

\[ pH = -\log\left( \frac{V_1 C_1 + V_2 C_2}{V_1 + V_2} \right) \]

Where:

\( V_1 \) — Volume of first solution (mL)
\( C_1 \) — Concentration of first solution (mol/L)
\( V_2 \) — Volume of second solution (mL)
\( C_2 \) — Concentration of second solution (mol/L)

Explanation: The equation calculates the weighted average concentration of hydrogen ions from both solutions, then converts it to pH scale.

3. Importance of pH Calculation

Details: Knowing the resulting pH of mixed solutions is crucial in chemistry labs, industrial processes, and environmental science to predict chemical behavior and reaction outcomes.

4. Using the Calculator

Tips: Enter volumes in milliliters (mL) and concentrations in moles per liter (mol/L). All volumes must be positive, and concentrations must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: Can this calculator mix acidic and basic solutions?
A: This version calculates simple mixing. For acid-base neutralization, a more complex calculator is needed.

Q2: What if I mix very dilute solutions?
A: The calculator will approach pH 7 (neutral) as concentrations approach zero.

Q3: Does temperature affect the calculation?
A: This calculator assumes standard conditions (25°C). pH values may vary slightly with temperature.

Q4: Can I mix more than two solutions?
A: For multiple solutions, you would need to extend the equation to include all terms.

Q5: What about weak acids/bases?
A: This calculator assumes strong acids/bases that fully dissociate. Weak electrolytes require different calculations.
