What species is classified as an Arrhenius base?

proton acceptors.

An Arrhenius base is one that produces OH^- in solution.

An Arrhenius base is a substance that, when dissolved in water, increases the concentration of hydroxide ions (OH-) in the solution. Examples of species that are classified as Arrhenius bases include hydroxides of alkali metals (such as sodium hydroxide - NaOH) and alkaline earth metals (such as calcium hydroxide - Ca(OH)2).

To determine the species classified as an Arrhenius base, we first need to understand what an Arrhenius base is. An Arrhenius base is a substance that, when dissolved in water, increases the concentration of hydroxide ions (OH-) in the solution.

Now, to find the species classified as an Arrhenius base, we can look at different compounds and see if they fit this description. Typically, metal hydroxides are considered Arrhenius bases. When metal hydroxides are dissolved in water, they release hydroxide ions, which increase the concentration of hydroxide ions in the solution.

Some examples of metal hydroxides that are classified as Arrhenius bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)₂).

So, to summarize, species classified as Arrhenius bases are typically metal hydroxides such as sodium hydroxide, potassium hydroxide, and calcium hydroxide.
