1. What is pH to Mole Calculation?

The pH to mole calculation converts pH values to hydrogen ion concentration [H+] using the formula [H+] = 10^(-pH). This is fundamental in chemistry for understanding acidity and basicity of aqueous solutions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( [H^+] \) — Hydrogen ion concentration (mol/L)
• \( pH \) — pH value (dimensionless)

Explanation: The pH scale is logarithmic, meaning each unit change represents a tenfold change in hydrogen ion concentration.

3. Importance of pH Calculation

Details: Accurate pH to mole conversion is essential for chemical reactions, biological systems, water treatment, and various industrial processes where acidity control is critical.

4. Using the Calculator

Tips: Enter pH value between 0 and 14. The calculator will compute the corresponding hydrogen ion concentration in moles per liter.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between pH and [H+]?
A: pH = -log[H+], so [H+] = 10^(-pH). They have an inverse logarithmic relationship.

Q2: What is the [H+] concentration at pH 7?
A: At pH 7 (neutral), [H+] = 10^(-7) = 0.0000001 mol/L or 100 nM.

Q3: How does pH affect chemical reactions?
A: pH influences reaction rates, equilibrium positions, and solubility of compounds in aqueous solutions.

Q4: Can this calculator be used for non-aqueous solutions?
A: This formula is specifically designed for aqueous solutions. Different relationships may apply in other solvents.

Q5: What are typical pH ranges?
A: Acidic solutions: pH < 7, Neutral: pH = 7, Basic solutions: pH > 7. Most biological systems operate between pH 6-8.
