Document Summary
Chapter 2: acids & bases: central to understanding organic chemistry: early chemists called compound that tasted sour acid (from acidus, latin for. Some familiar acids are citric acid (in lemons & other citrus fruits), acetic acid (in vinegar), & hydrochloric acid (in stomach acid sour taste associated with vomiting): compounds that neutralize acids, thereby destroying their acidic properties. Glass cleaners & solutions designed to unclog drains are familiar alkaline solutions. Ex: in reaction, hcl is acid because it loses proton, & water is base because it gains proton. Both acid & base must be present in acid base reaction, because acid cannot lose proton unless base is present to accept it. 2 half-headed arrows are used to designate reversible reactions. o: when acid loses proton, resulting species without proton = conjugate base of acid. Thus, cl- is conjugate base of hcl, & h. When base gains proton, resulting species with proton = conjugate acid of base.
