hydronium

The effective diameter for the hydronium ion is 9Å.

For many strong acids, it is possible to form crystals of their hydronium salt that are relatively stable.

Hydronium is often used as an approximation of the state of protons in water.

In pure water, there is an equal number of hydroxide and hydronium ions.

This leads to hydronium playing a very important role in interstellar ion-neutral chemistry.

Hydronium ions are acids according to all three definitions.

Hydronium is the cation that forms from water in the presence of hydrogen ions.

In the following equation, hydronium and hydroxide combine to form water:

They lose a proton to a water molecule to form H3O+, the hydronium ion.

The resulting hydronium ions are few and short-lived.

The hydronium ion needed to do so was produced during the activation of the sulphur atom in an earlier step.

Hydronium ions inevitably resulted wherever acid was added to an aqueous medium.

For example, a protonated hydroxyl group is an oxonium ion, but not a hydronium.

This reaction is best thought of as the formation of hydronium ions:

As weak acids themselves, they were terribly susceptible to the hydronium ions that swarmed in their midst.

In acidic solutions, hydronium is the more active, its excess proton being readily available for reaction with basic species.

Considering the hydronium ion, the actual net ionic reaction occurring is:

Thus, an Arrhenius acid can also be described as a substance that increases the concentration of hydronium ions when added to water.

An Arrhenius base, on the other hand, is a substance which decreases the concentration of hydronium ions when dissolved in water.

Reaction with hydronium from water and carbon monoxide regenerates the metal carbonyl complex.

The commercial product is the hydronium salt of the hexachloroplatinate(IV) anion.

Hydrogen ion channels detect the concentration of hydronium ions that are formed from acids and water.

It is the presence of hydronium ions relative to hydroxide that determines a solution's pH.

In fact, the hydronium ion (HO) occurs, produced by the following reaction:

Superacids can permanently protonate water to give ionic, crystalline hydronium "salts".
