1. Highland Science Department Double Displacement Details 3 types of double displacement reactions:

2. Highland Science Department Double Displacement Details 3 types of double displacement reactions: 1. forms a solid (precipitate) 2. forms a gas 3. forms water

3. Highland Science Department Double Displacement Details 1. d.d. reactions producing precipitates Precipitate: a insoluble solid formed by a chemical reaction between two soluble compounds

4. Highland Science Department Double Displacement Details 1. d.d. reactions producing precipitates Precipitate: a insoluble solid formed by a chemical reaction between two soluble compounds Solubility Guidelines: a summary indicating whether the products of double displacement reactions are soluble or insoluble.

6. Double Displacement Details e.g. magnesium chloride & lead (II) acetate

7. Highland Science Department Double Displacement Details e.g. magnesium chloride & lead (II) acetate magnesium + lead (II)  magnesium + lead (II) chlorideacetateacetatechloride

8. Highland Science Department Double Displacement Details e.g. magnesium chloride & lead (II) acetate magnesium + lead (II)  magnesium + lead (II) chlorideacetateacetatechloride (soluble) (insoluble)

9. Highland Science Department Double Displacement Details e.g. magnesium chloride & lead (II) acetate magnesium + lead (II)  magnesium + lead (II) chlorideacetateacetatechloride (soluble) (insoluble) MgCl 2(aq) + Pb(CH 3 COO) 2(aq)  Mg(CH 3 COO) 2(aq) + PbCl 2(s)

10. Highland Science Department Double Displacement Details 2. d.d. reactions producing gases: Two types 1. acid + compound containing carbonate ions produce an ionic compound + water + carbon dioxide

11. Highland Science Department Double Displacement Details 2. d.d. reactions producing gases Two types 1. acid + compound containing carbonate ions produce an ionic compound + water + carbon dioxide 2. compound containing ammonium ions + base (hydroxide) produce an ionic compound + water + ammonia gas
