Presentation Transcript

  1. Acids & Bases Strength & Neutralization

  2. Acid Strength • Strong Acids -completely ionize in an aqueous solution • Ex. HCl, H2SO4 • Weak Acids - only slightly ionize in an aqueous solution

  3. Base Strength • Strong Bases – completely dissociate into metal ions & hydroxide ions in aqueous solution • NaOH • Weak Bases – react w/ water to form hydroxide ions & the conjugate acid • Ammonia

  4. Types of Indicators • Litmus paper • Acids – Blue turns to Red • Bases – Red turns Blue • Phenol Red • Acids turn YELLOW • Bases turn PINK • pH paper • Tests all 14 pH levels, each having a different color

  5. Neutralization Rxns • Acid + Base = Salt + Water • Remember “Salts” are compounds made of an anion from an acid & a cation from a base!

  6. Titrations • A way to find the concentration of one solution, when you know the concentration of the other solution….

  7. Buffers • A solution of a weak acid & a weak base • A buffer keeps the pH relatively constant if a small amt of acid or base is added
