Fluoride mimics the nucleophilic hydroxyl ion in these enzymes' active sites.

Actually, cyanoacrylate does require a chemical trigger to cause it to set, but with amazing convenience, that trigger is the hydroxyl ions in common water.

As a result, hydroxyl ions serve as tracer molecules.

The molecules of this acrylic resin react on contact with the hydroxyl ions found in water.

In hydroxides, the dominant anion is the hydroxyl ion, OH.

This means that it contains a moderate or high proportion of hydroxyl ions (pH value greater than 7).

It forms a series with the more common hydroxylherderite, which has more hydroxyl ion than fluoride.

In this case the net result is a relative excess of hydroxyl ions, giving a basic solution.

In an aqueous base, hydroxyl ions are better nucleophiles than polar molecules such as water.

A base is any molecule when dissolved in water produces hydroxyl ions, designated as (OH)-1.
