For a neutral solution at 25 °C, what is the concentration of H3O+ ions?

Understand the Problem

The question is asking for the concentration of H3O+ ions in a neutral solution at a specific temperature (25 °C). In a neutral solution at this temperature, the concentration is typically defined based on the self-ionization of water.

Answer

1.0 * 10^-7 M

The final answer is 1.0 * 10^-7 M

Answer for screen readers

The final answer is 1.0 * 10^-7 M

More Information

At 25°C, pure water has a dissociation constant (Kw) of 1.0 x 10^-14, thus making the concentration of hydronium ions [H3O+] in a neutral solution 1.0 x 10^-7 M. This is due to water self-ionizing to produce equal amounts of H3O+ and OH- ions.

Tips

A common mistake is confusing the neutral concentration value with that of an acidic or basic solution, where [H3O+] would be higher or lower, respectively.
