Frequently asked questions
- What is the difference between H⁺ and H₃O⁺?
- In water, free protons (H⁺) immediately bond to water molecules to form hydronium ions (H₃O⁺). The two notations are used interchangeably in pH calculations.
- What [H⁺] corresponds to neutral water?
- At 25 °C, pure water has [H⁺] = [OH⁻] = 1×10⁻⁷ mol/L, giving pH = 7.
