Presentation Transcript

  1. NEUTRALIZATION

  2. NEUTRALIZATION The process by which an acid or base is made neutral. ACID BASE (characterized by H+ ions) (characterized by OH-ions) Mix them together in equal amounts (same # of H+ and OH – ions) NEUTRALZATION

  3. IMPORTANT! IF………THE SOLUTION IS NEUTRAL ALSO… • By adding a base to an acid you can neutralize the acid (or lower the concentration of acid) • By adding an acid to a base you can neutralize the base (or lower the concentration of base)

  4. EXAMPLES • Limestone (base) used to treat acid waste (acidic) • Baking soda (base) used to neutralize common household acid spills • Bile in liver is added to food to adjust acidity of mixture • Anti-acids like Rolaids are used to lower acid content in stomach http://www.wpbschoolhouse.btinternet.co.uk/page03/AcidsBasesSalts.htm

  5. CHEMICAL REACTIONS When neutralizing acids with bases or vice versa, the product is a salt and water NaOH (sodium hydroxide) + HCl (hydrochloric acid) NaCl (sodium chloride) + H2O (base)(acid)(salt) (water) REACTANTS PRODUCTS

  6. PRACTICE PROBLEMS • Study guide, Module 3, page 34, 35 • WORKSHEET # 9
