hydroxide ion
hydroxyl ion

This is a stronger base than the hydroxide ion and so cannot exist in aqueous solution.

At anode, hydroxide ions react with the fuel to produce water and electrons.

It is a strong base, even stronger than the hydroxide ion.

This is an unusual form of hydrogen bonding since the two hydroxide ion involved would be expected to point away from each other.

The hydroxide ion may act as a base catalyst.

Various nitrogen oxides can also react with hydroxide ions to form acids.

Because it forms hydroxide ions, this process is strongly affected by the presence of acid.

Hydrogen gas and hydroxide ions are formed at the cathode.

Asp-123 coordinates to Mg2+ which in turn stabilizes the leaving hydroxide ion.

This mineral contains hydroxide ions, which indicates the presence of water when the minerals were formed.
