What is the Arrhenius acid and what is the Arrhenius base in the above reaction?

To determine the Arrhenius acid and base in a chemical reaction, it is important to understand the concept of Arrhenius acids and bases.

According to the Arrhenius theory, an acid is a substance that increases the concentration of hydrogen ions (H+) in an aqueous solution, while a base increases the concentration of hydroxide ions (OH-) in an aqueous solution.

Unfortunately, you haven't provided any specific reaction or context for the above reaction. Therefore, I cannot determine the Arrhenius acid and Arrhenius base without more information.

To find the Arrhenius acid and base in a reaction, you should look for species that donate or accept hydrogen ions (H+) or hydroxide ions (OH-) respectively. These species can then be determined as the acid or base based on their behavior according to the Arrhenius theory.
