Document Summary

Acids and bases were first defined by swedish chemist svante arrhenius in 1884. A compound was an acid or base depending on the kinds of ions formed when the compound was added to water. An arrhenius acid is any species that increases the concentration of h+ ions in an aqueous solution for example, hcl, hbr, etc. An arrhenius base on the other hand is defined as any species that increases the concentration of oh- ions in an aqueous solution like naoh. These definitions were further improved by both thomas lowry and j. n. Br nsted who defined an acid as a compound that donates a proton and a base as a compound that can accept a proton. Acids generally have a sour taste and have a ph less than 7. Bases are slippery to the touch and have a bitter taste. The stronger an acid or base, the more corrosive it is.
