Noun
hydronium (plural hydroniums)
(inorganic chemistry) The hydrated hydrogen ion, H3O.
A freezing-point depression study determined that the mean hydration ion in cold water is approximately Hmain Omain (Hmain O) 6 : citation on average, each hydronium ion is solvated by 6 water molecules which are unable to solvate other solute molecules. Source: Internet
In organic syntheses, such as acid catalyzed reactions, the hydronium ion ( Hmain Omain ) can be used interchangeably with the H + ion; choosing one over the other has no significant effect on the mechanism of reaction. Source: Internet
Conversely, to qualify as an Arrhenius base, upon the introduction to water, the chemical must either cause, directly or otherwise: *a decrease in the aqueous hydronium concentration, or *an increase in the aqueous hydroxide concentration. Source: Internet
For example, a protonated hydroxyl group is an oxonium ion, but not a hydronium. Source: Internet
If mineral acid is added to the acetic acid mixture, increasing the concentration of hydronium ion, the amount of dissociation must decrease as the reaction is driven to the left in accordance with this principle. Source: Internet
In acidic solutions, hydronium is the more active, its excess proton being readily available for reaction with basic species. Source: Internet
