Term 4 - Chalk Talk
We learned, or at least reinforced, most of our knowledge regarding acids and bases. In the first question, we confirmed that acids are covalent compounds and acids are ionic compounds. In the second question, we mostly agreed that Arrhenius' acid and base theory was the best. However, we were informed that Lewis' is much more extensive and broader.
