Study Notes

Double Replacement Reactions

  • Double replacement reactions typically involve two ionic solutions producing two new ionic compounds.
  • One of the new compounds often forms a precipitate which is an insoluble solid. This solid settles out of solution.
  • Another compound may also form a precipitate or remain dissolved.
  • General form: AB(aq) + CP(aq) → AD(aq) + CB(s)
  • Example 1: Pb(NO₃)₂ + 2NaI → 2NaNO₃ + PbI₂
    • Lead (II) nitrate solution mixed with sodium iodide solution yields lead (II) iodide as a precipitate.
  • Example 2: 3NaOH + FeCl₃ → 3NaCl + Fe(OH)₃
    • Sodium hydroxide solution mixed with iron (III) chloride solution produces iron (III) hydroxide precipitate.

Neutralization (Acid-Base) Reactions

  • Acids are compounds that produce H⁺ ions in solution. Acidic solutions have a pH less than 7.
  • Bases are compounds that produce OH⁻ ions in solution. Basic solutions have a pH greater than 7.
  • When an acid and a base combine, they neutralize each other forming a salt and water.
  • General form: HX + MOH → WX + H₂O
    • X represents a negative ion, M represents a positive ion
  • Example 1: Phosphoric acid (H₃PO₄) is a main ingredient in rust remover. Iron (II) hydroxide (Fe(OH)₂) reacts with phosphoric acid to dissolve it.
  • 2H₃PO₄ + 3Fe(OH)₂ → Fe₃(PO₄)₂ + 6H₂O

Combustion Reactions

  • Combustion is the rapid reaction of a compound or element with oxygen forming oxides and producing heat.
  • Common examples involve organic compounds reacting with oxygen to form carbon dioxide and water.
  • General form: CxHy + O₂ → CO₂ + H₂O
  • Example 1: Methane (natural gas) combustion
  • CH₄ + 2O₂ → CO₂ + 2H₂O
  • Example 2: Acetylene combustion used in welding torches
  • 2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O
  • Example 3: Glucose combustion
  • C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
