Document Summary

Smallest useful particle in all of us: electrons and protons (hydrogen is the smallest, electrons are smallest, protons are the next smallest after electrons. Nature uses 2 particles in everything that it does. Acids and bases are moving protons- this is why we are interested in them. Mostly use the bronsted-lowry definition for acid and bases: an acid is a proton donor. Result is a proton that has lost its electron. Not going to be happy without the electron. This system goes from high energy to low energy. This system goes from a happy state to an unhappy state: a base is a proton acceptor. B: (base) + h+ bh+ (conjugate acid) Base goes around looking for a proton. Once it gains the proton its no longer neutral: always have to have an acid reaction occurring at the same time as the base reaction. For a strong acid ha: ha + h2o: h3o+ a-
