What substance that releases hydroxide ions into water?

A substance that releases hydroxide ions into water is a base. Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). When these substances dissolve in water, they dissociate into ions, including hydroxide ions (OH-), which result in an alkaline solution.


Does sodium hydroxide release protons when added to water?

No. Sodium hydroxide releases hydroxide ions, which actually take protons out of the solution. This qualifies sodium hydroxide as a base.


What is the term for a subsatnce that relaeses hydroxide ions in water?

A base releases hydroxide ions in solution.


What is the substance that releases in OH negative ion and water?

The substance that releases hydroxide ions (OH⁻) in water is typically a base. When a base, such as sodium hydroxide (NaOH), dissolves in water, it dissociates into sodium ions (Na⁺) and hydroxide ions (OH⁻). This increase in hydroxide ion concentration is what characterizes the solution as basic or alkaline.


What does a base release when it is dissolved?

A base releases hydroxide ions (OH-) when it is dissolved in water. These hydroxide ions can then react with acids to neutralize them and form water.


What produces OH ions when added to water?

Substances that produce OH- ions when added to water are known as bases, or alkaline substances. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which dissociate in water to release hydroxide ions. These hydroxide ions then react with water molecules to form hydroxide ions (OH-) and hydronium ions (H3O+), leading to the characteristic alkaline properties of bases.


Chemical which takes up hydrogen ions or releases hydroxide ions?

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).


What is a substance which when added to water produces hydroxide ions?

A substance that, when added to water, produces hydroxide ions is called a base. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). These compounds dissociate in water to release hydroxide ions (OH⁻), increasing the solution's pH and making it alkaline.


A substance that releases hydroxide ions into water?

A substance that releases hydroxide ions into water is called a base. Bases tend to have a bitter taste, feel slippery to the touch, and turn red litmus paper blue. Examples of bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).


What will happen if a base is added to water?

When a base is added to water, it will dissociate, releasing hydroxide ions (OH-) into the solution. These hydroxide ions will react with water molecules to increase the concentration of OH- ions and decrease the concentration of H+ ions, resulting in an increase in pH.


What ion increases concentration when a strong base is added to water?

Hydroxide ions (OH-) increase in concentration when a strong base is added to water. This is because strong bases dissociate completely in water to release hydroxide ions, which then increase the overall concentration of hydroxide ions in the solution.


What causes a base to dissociate?

The polar water molecules pull on the ions of the base.
