CHE 1302 Lecture Notes - Lecture 15: Carboxylic Acid, Sulfuric Acid, Ph
Document Summary
8: acids & bases are de ned by their properties. Acids: taste sour, turn blue litmus paper red, react with metals to form h2, neutralize a base, & then lose acidic property, common strong acid: hcl, common weak acid: ch3cooh. Bases: taste bitter, turn red litmus blue, feel slippery on skin, neutralize acid, & then lose basic property, common strong base: naoh, common weak base: nh3, arrhenius de nition. Describes what speci cally happens when things dissolve in h20. Also explains neutralization: problems with arrhenius de nition. Tells nothing about reactions that don"t involve h2o. Many bases don"t contain oh: br nsted-lowry de nition. De nes acids/bases in terms of proton (h+) transfer. Acid-base reaction is proton transfer process: conjugate pairs. Acid & base that differ from each other by h+ Contains acid & base: identical besides: One doesn"t: conjugate base of acid. A- is the conjugate base of acid ha: conjugate acid of base.
