  1. 6.2 Types of Chemical Reactions Single and Double Displacement Neutralization

  2. 4. Single Displacement Element + Ionic Compound  New element + New ionic Compound In general, A + BC  B + AC if the A is a metal it replaces a metal Notice: A replaces B A + BC  C + BA if the A is a non-metal it replaces a non-metal Notice: A replaces C

  3. Example Predict the products made when: • sodium chloride reacts with Calcium • Aluminum oxide reacts with phosphorus

  4. 5. Double Displacement • Positive or negative ions in two dissolved ionic compounds (aqueous) switch places Compound + compound  new compound + new compound In general, AB + CD  AD + CB Notice how A and C (both metals) traded places

  5. Example Predict the products made when • magnesium hydroxide reacts with silver nitrate • Potassium iodide reacts with calcium chloride

  6. 6. Neutralization • Special kind of double displacement reaction • Only happens between an acid (has H as the metal) and base (has OH as the non-metal) • Always makes a SALT and WATER In general, HB + XOH XB + H2O (also written as HOH)

  7. Example Predict the products made when: • hydrochloric acid reacts with lithium hydroxide • Sulfurous acid reacts with Sodium hydroxide
