  1. Topic: Neutralization Reaction Do Now:

  2. Neutralization Reactions • DR rxn + → Base Salt + Water • Acid • HX(aq) + MOH(aq)→ MX(aq) +H2O(l) Why is it called a neutralization reaction?

  3. Hydrochloric Acid + Sodium Hydroxide yields ?? • HCl(aq) + • NaOH(aq) •  NaCl(aq) + • H2O(l) Is it balanced?? Complete ionic equation H+1(aq) + Cl-1(aq) + Na+1(aq) + OH-1(aq) H2O(l) + Na+1(aq)+Cl-1(aq) Net ionic equation H+1(aq) + OH-1(aq) H2O(l)

  4. Sulfuric Acid + Calcium Hydroxide yields?? H2SO4(aq) + Ca(OH)2(aq)  • CaSO4(aq) + H2O(l) 2 Is it balanced?? Complete ionic equation 2H+1(aq) + SO4-2(aq) + Ca+2(aq) + 2OH-1(aq) 2H2O(l) + Ca+2(aq)+ SO4-2(aq) Net ionic equation 2H+1(aq) + 2OH-1(aq) 2H2O(l)

  5. H2SO4(aq) + Ca(OH)2(aq)  CaSO4(aq) + H2O(l) Sulfuric Acid + Calcium Hydroxide H2SO4 + Ca(OH)2→ CaSO4 + 2 H2O

  6. For any neutralization reaction between an acid & base: net ionic equationis always H+1(aq) + OH-1(aq)  H2O(l) At neutralization point: # moles H+1 = # moles OH-1

  7. pH < 7 pH  pH = 7 pH > 7 pH  pH = 7 pH changes during neutralization • Start with an acid • Add a base • At neutralization • Start with a base • Add an acid • At neutralization
