Arrhenius model considers a base a compound that produces OH(-)

H2SO4 produces H(+) and is an acid

C6H12O6 is an organic product, sugar, that does not produce OH(-)

HOClO2 = HClO3, which produces H(+) and is an acid

NH3 is believed to ionize in water and produce NH4(+) and OH(-).

As per this the answer is NH3.

Nevertheless, NH3 is not a good example of bases as per Arrhenius model, because it is not so evident that NH3 produces OH(-).

Sodium hydroxide (NaOH) is an Arrhenius base, as NaOH is an ionic compound that dissociates into Na + and OH− ions when dissolved in water.

Further explanation

Acids and bases are two classes of chemicals that are very commonly found around us. For example, vinegar, citric acid, and acid in the stomach are classified as acid, while whiting and soda are classified as basic. Acids and bases have different properties. At first, acids and bases are distinguished by taste, where acids are sour while bases are bitter and slippery like soap. However, in general, acidic and basic substances are corrosive and toxic, especially in the form of high levels of the solution so that it is very dangerous if tested for its nature by the method of feeling it.

According to Arrhenius's theory, acids are defined as compounds that if dissociated in an aqueous solution liberate H + (hydrogen ions). A base is defined as a compound that dissociates in an aqueous solution liberating OH− (hydroxide ions).

Arrhenius Acid-Base Theory

This theory was first put forward in 1884 by Svante August Arrhenius. According to Arrhenius, the definitions of acids and bases, namely:

  • acid is a compound that dissolves in water releasing H + ions.
  • A base is a compound which, when dissolved in water, releases OH− ions.

Hydrochloric acid (HCl) which is very soluble in water is classified as Arrhenius acid, as HCl can decompose into H + and Cl− ions in water. Unlike the case with methane (CH4) which is not Arrhenius acid because it cannot produce H + ions in water even though it has H. Sodium hydroxide (NaOH) including Arrhenius bases, as NaOH is an ionic compound which dissociates into Na + and OH− ions when dissolved in water. The concept of Arrhenius acids and bases is limited to the condition of water as a solvent.
