# What substance is always a product when an Arrhenius acid in an aqueous solution reacts with an Arrhenius base in an aqueous solution?

Water

#### Explanation:

An "Arrhenius" acid or base is the earliest and most restrictive of acid/base definitions, limiting them to observed proton ($\left[{H}^{+}\right]$) concentrations in solution. The product of an Arrhenius acid-base reaction will always be water.

${H}^{+} + O {H}^{-} \to {H}_{2} O$
