Problem: Complete Table 1 by noting how each theory defines acids and bases. Also, list chemical reactions that demonstrate the action of each acid or base. For example, in the reaction HA --> H+ + A-, HA acts as an Arrhenius acid. Firstly, I'd like to check my answers for the chemical reactions part. Arrhenius: Acids- HA --> H+ + A- Bases- XOH --> X+ + OH- Bronsted-Lowry: Acids- ? Bases- ? This is all that was listed: HCl + H2O <===> H3O+ + Cl- HNO3 + H2O <===> H3O+ + NO3- HC2H3O2 + H2O <===> H3O+ + C2H3O2- NH3 + H2O <===> NH4+ + OH- I don't really understand them though... Lewis: Acids- HNO3 => H+1 + NO3-1 Bases- ? To be honest, I don't really understand what I'm doing. I started reading what I was assigned but I got stuck on Bronsted-Lowry's theory so I took out the book my public school loaned me. Since this is a new chapter, I started off reading the basics and worked my way up to the three theories mentioned on my lesson page. Doing so only manged to confuse me more because now I'm wondering where the "A" and "X" are coming from in my first answer. Maybe someone could explain this to me or give me some sites?
