1. 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: A) sodium chloride reacts with Calcium B) 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 A) magnesium hydroxide reacts with silver nitrate B) 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 + H 2 O (also written as HOH)

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