Hydronium, Hydroxide, and the pH Scale (16.1.2) Flashcards
• A proton (H+) can be solvated by varying numbers of water molecules; hydronium ion (H3O+) is the simplest expression of this hydration.
• A proton (H+) can be solvated by varying numbers of water molecules; hydronium ion (H3O+) is the simplest expression of this hydration.
• The dissociation constant of water (Kw) represents the self-ionization of water (H2O splitting into H+ and OH–) and has a value of 1 x 10–14 at room temperature (25˚C).
• The dissociation constant of water (Kw) represents the self-ionization of water (H2O splitting into H+ and OH–) and has a value of 1 x 10–14 at room temperature (25˚C).
• The pH of a solution is the negative logarithm of its hydronium ion concentration.
• The pH of a solution is the negative logarithm of its hydronium ion concentration.
