Identify each substance as an acid or a base and write a chemical equation showing how it is an acid or a base according to the Arrhenius definition. c. KOH(aq)

Video transcript

Hey everyone, we're asked to identify whether barium hydroxide is an Arrhenius acid or an Arrhenius base and to write a chemical equation showing it as an acid or a base, as we've learned, we know that an Arrhenius acid is one that increases the concentration of our hydrogen ion, while an arena space is one that increases the concentration of our hydroxide ion. Now when we write our chemical equation, we have our barium hydroxide and we see that it associates into our barium ion plus our hydroxide ion. And to balance this out, we add a two prior to our hydroxide ion. So as we can see right here, we had an increase in the concentration of our hydroxide ions, which means that we have an Arrhenius base. So I hope this made sense. And let us know if you have any questions.
