Document Summary

Chemistry unit 7: module 1 acid-base chemistry. Autoionization the spontaneous dissociation into ions, as exemplified in water. Traditionally, chemists distinguished between acids and bases based on taste. Acids have a sour taste (ex: acetic acid/vinegar: this sour taste arises from the presence of phosphoric and carbonic acids. Bases have a bitter taste: ex: coca leaf has a bitter taste as a result of cocaine, which is an alkaloid. Arrhenius played a key role in the understanding of the physical chemistry of electrolytes. Acids species that ionize in water to generate a proton, or h+ Bases species that ionize in water to generate hydroxide ions, oh- Arrhenius definition of an acid-base reaction: an acid-base reaction is the neutralization of an aqueous proton with a hydroxide ion: only applicable to protic acids and metal hydroxides in water (excludes a number of species) An acid is a proton, or h+ donor. Every acid-base reaction has a conjugate acid and conjugate base as products.
