There are many. Water itself contains some free hydroxide ions. More common ones include Sodium Hydroxide solution, Potassium Hydroxide Solution, Slaked Lime Slurry, Concrete, Cement etc
One example of a chemical containing hydroxide ions is sodium hydroxide, which has the chemical formula NaOH. When dissolved in water, sodium hydroxide dissociates into sodium ions (Na+) and hydroxide ions (OH-). Hydroxide ions are strong bases and can react with acids to form water and a salt.
Hydroxide ions are anions with the chemical formula (OH)-.
Lye, containing hydroxide ions, is a base. Bases are substances that release hydroxide ions (OH-) in water solution.
Iron hydroxide is a chemical compound made of iron (Fe) and hydroxide (OH) ions. It is commonly formed when iron reacts with water or hydroxide-containing compounds.
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
Basic solution
Formula: OH-
A base is a chemical that releases hydroxide ions (OH-) when dissolved in water. Bases are also known as alkalis. Examples include sodium hydroxide (NaOH) and ammonia (NH3).
Hydroxide ions are represented by the chemical formula OH-. In aqueous solutions, they can also be denoted as [OH]-.
The chemical symbol for hydroxide ions is OH-.
The chemical formula of magnesium hydroxide is Mg(OH)2; this compound is extremely low soluble in water.
Hydronium hydroxide is not a recognized chemical compound. There is no stable form of hydronium hydroxide because hydronium ions (H3O+) and hydroxide ions (OH-) react to form water.
