Any Arrhenius base will produce the OH- ion. Ammonia is a common example. Example- NH3(g) + H2O(l) -> NH4+(aq) + OH−(aq)
Other examples include:
natural dissociation of water: H2O -> OH- + H3O+
sodium hydroxide: NaOH(s)->Na+(aq)+OH-(aq)
Compounds that produce hydroxide ions in solution are called bases. Some common examples include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). When dissolved in water, these compounds release hydroxide ions (OH-) which can react with acids to form water and a salt in a neutralization reaction.
Arrhenius bases produce OH- ions by definition when dissolved in water. A Bronsted - Lowry base can produce OH- ions, but only has to produce a proton accepting group by definition. A Lewis base is defined as an electron donating group, which hydroxide ion is. So, basic compounds do produce OH- ions when dissolved in water, but not in all cases.
Compounds that form hydroxide ions in solution include metal hydroxides like sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These compounds dissociate in water to release hydroxide ions (OH-) and cations.
Bases produce hydroxide ions (OH-) in solution. When a base dissolves in water, it donates hydroxide ions, which can then react with acids to neutralize them and form water.

Hydroxide Ions
Bases produce hydroxide ions (OH-) in solution. When a base dissolves in water, it donates hydroxide ions, which can then react with acids to neutralize them and form water.
Bases produce hydroxide ions (OH-) in solution.
Bases produce hydroxide ions (OH-) when they dissociate in water. The hydroxide ions are formed as a result of the base accepting a proton (H ion) from the water molecule, creating hydroxide ions and leaving behind a hydroxide ion. This process increases the concentration of hydroxide ions in the solution, making it basic.
The hydroxide ion (OH-) is always present in alkalis. Alkalis are chemical compounds that produce hydroxide ions in solution and have a pH greater than 7.
A salt
Yes, alkalis produce hydroxide ions (OH-) in solution. Alkalis are soluble bases that dissociate in water to release hydroxide ions, which are responsible for their alkaline properties.
