Question

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

Answer 1

Water

Explanation:

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

`H^+ + OH^(-) -> H_2O`
