When water dissociates, what is released more: H+ or OH-? Explain.

When water (H₂O) dissociates, it produces equal amounts of hydrogen ions (H⁺) and hydroxide ions (OH^–). The dissociation of water can be represented by the following equation:

H₂O <=> H⁺ + OH^–

This equilibrium means that for every molecule of water that dissociates, one hydrogen ion and one hydroxide ion are produced. Therefore, the concentration of H⁺ ions and OH^– ions are equal in pure water at 25°C, both being 1.0 x 10^-7 moles per liter.

It’s important to note that while pure water maintains this balanced state, the addition of acids or bases can disturb this equilibrium. Acids increase the concentration of H⁺ ions, while bases increase the concentration of OH^– ions. But in the case of dissociation of pure water alone, the release of H⁺ and OH^– ions is always equal.
