The concentration of H3O+ ions in pure water at 25°C is correctly represented by:
**1.0 × 10^-7 mol/L**
This is because pure water is neutral and has equal concentrations of H3O+ and OH- ions, both being 1.0 x 10^-7 mol/L.
**1.0 × 10^-7 mol/L**
This is because pure water is neutral and has equal concentrations of H3O+ and OH- ions, both being 1.0 x 10^-7 mol/L.
