Acid
The answer is: They increase the concentration of hydroxide ions in aqueous solution.
Basic solutions are solutions that have more than a 1E-7 concentration of hydroxide ion. Thus, solutions with "extra" hydroxide ions are basic. On the other hand, solutions with extra hydrogen (hydronium) ions are acidic.
Hydrogen gas is formed when aluminum metal reacts with aqueous sodium hydroxide. The reaction produces aluminum hydroxide and hydrogen gas.
Aqueous refers to water, so the liquid in an aqueous solution is water.
No, you mixed it up. Hydronium H3O+ from strong acid and Hydroxide OH- from strong base (alkaline)

Ahh, Svante Arrhenius. Cool guy. Wish I'd met him. Anyway, Arrhenius created a definition for an acid and for a base -- Acid - a substance which produces hydronium ions (H3O+) in aqueous solution Base - a substance which produces hydroxide ions (OH-) in aqueous solution That's it!

Hydroxide ions are represented by the chemical formula OH-. In aqueous solutions, they can also be denoted as [OH]-.
Saponification is a process of converting esters into soaps and alcohols by the action of aqueous alkali (for example, aqueous sodium hydroxide solutions).
The reaction between sodium hydroxide and sulfuric acid produces sodium sulfate and water. Sodium hydroxide (NaOH) reacts with sulfuric acid (H2SO4) in a neutralization reaction to form sodium sulfate (Na2SO4) and water (H2O).
If very dilute solutions are included, the pH value can be anything above 7.0 up to at least 14 and possibly higher.
According to Arrhenius theory, a base is a substance that produces hydroxide ions (OH-) in aqueous solution. Bases are characterized by their ability to accept protons (H+) and release hydroxide ions in a chemical reaction. Examples of bases in aqueous solutions include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
An aqueous solution that contains more hydroxide ions than hydronium ions is considered to be basic or alkaline. This imbalance in ion concentration leads to a pH greater than 7. Examples of such solutions include sodium hydroxide (NaOH) and potassium hydroxide (KOH) solutions.
