Edit Comment Close Premium member Presentation Transcript The Chemistry of Acids and Bases : The Chemistry of Acids and Bases Unit IV Acid and Bases : Acid and Bases Acid and Bases : Acid and Bases Acid and Bases : Acid and Bases Acids : Acids Have a sour taste. Vinegar is a solution of acetic acid. Citrus fruits contain citric acid. React with certain metals to produce hydrogen gas. React with carbonates and bicarbonates to produce carbon dioxide gas Have a bitter taste. Feel slippery. Many soaps contain bases. Bases Some Properties of Acids : Some Properties of Acids Produce H+ (as H3O+) ions in water (the hydronium ion is a hydrogen ion attached to a water molecule) Taste sour Corrode metals Electrolytes React with bases to form a salt and water pH is less than 7 Turns blue litmus paper to red “Blue to Red A-CID” Some Properties of Bases : Some Properties of Bases Produce OH- ions in water Taste bitter, chalky Are electrolytes Feel soapy, slippery React with acids to form salts and water pH greater than 7 Turns red litmus paper to blue “Basic Blue” Some Common Bases : Some Common Bases NaOH sodium hydroxide lye KOH potassium hydroxide liquid soap Ba(OH)2 barium hydroxide stabilizer for plastics Mg(OH)2 magnesium hydroxide “MOM” Milk of magnesia Al(OH)3 aluminum hydroxide Maalox (antacid) Acid/Base definitions : Acid/Base definitions Definition #1: Arrhenius (traditional) Acids – produce H+ ions (or hydronium ions H3O+) Bases – produce OH- ions (problem: some bases don’t have hydroxide ions!) Slide 10: Arrhenius acid is a substance that produces H+ (H3O+) in water Arrhenius base is a substance that produces OH- in water Acid/Base Definitions : Acid/Base Definitions Definition #2: Brønsted – Lowry Acids – proton donor Bases – proton acceptor A “proton” is really just a hydrogen atom that has lost it’s electron! Slide 12: A Brønsted-Lowry acid is a proton donor A Brønsted-Lowry base is a proton acceptor acid conjugate base base conjugate acid ACID-BASE THEORIES : ACID-BASE THEORIES The Brønsted definition means NH3 is a BASE in water — and water is itself an ACID Conjugate Pairs : Conjugate Pairs Learning Check! : Learning Check! Label the acid, base, conjugate acid, and conjugate base in each reaction: HCl + OH- ? Cl- + H2O H2O + H2SO4 ? HSO4- + H3O+ You do not have the permission to view this presentation.
