  1. Highland Science Department Neutralization

  2. Highland Science Department Neutralization Neutralization Reaction: a double displacement reaction between an acid and a base producing water and a salt

  3. Highland Science Department Neutralization Neutralization Reaction: a double displacement reaction between an acid and a base producing water and a salt e.g. NaOH(aq)+ HCl(aq) H2O(l) + NaCl(aq)

  4. Highland Science Department Neutralization Neutralization Reaction: a double displacement reaction between an acid and a base producing water and a salt e.g. NaOH(aq) + HCl(aq) H2O(l) + NaCl(aq) H+ and OH- combine into H2O Na+ and Cl- combine into NaCl

  5. Highland Science Department Neutralization Neutralization Reaction: a double displacement reaction between an acid and a base producing water and a salt e.g. NaOH(aq) + HCl(aq) H2O(l) + NaCl(aq) H+ and OH- combine into H2O Na+ and Cl- combine into NaCl salt: a compound composed of a metal cation from a base and an anion from an acid

  6. Highland Science Department Neutralization Acid-Base Titration: a procedure used to determine the concentration of a solution by reacting a known volume of that solution with a measured volume of a solution that has a known concentration.

  7. Highland Science Department Neutralization Acid-Base Titration: a procedure used to determine the concentration of a solution by reacting a known volume of that solution with a measured volume of a solution that has a known concentration. acid-base indicator is added to reveal when the mixture has a neutral pH.

  8. Highland Science Department Neutralization titrant: the solution with a known concentration, slowly added to the solution with unknown concentration

  9. Highland Science Department Neutralization titrant: the solution with a known concentration, slowly added to the solution with unknown concentration burette: a clear tube with volume markings along its length and a tap at the bottom to slowly release titrant

  10. Highland Science Department Neutralization titrant: the solution with a known concentration, slowly added to the solution with unknown concentration burette: a clear tube with volume markings along its length and a tap at the bottom to slowly release titrant equivalence point: when the colour of the indicator, indicates that the amount of titrant is just enough to react with all the reactant in the sample -indicated by a neutral pH

  11. Highland Science Department Neutralization Calculations e.g. 1. a 0.1250 mol/L solution of hydrochloric acid was used to neutralize a 25.00 mL sample of potassium hydroxide solution. If it took 32.86 mL of hydrochloric acid what is the concentration of the potassium hydroxide solution?

  12. Highland Science Department Neutralization Calculations e.g. 1. a 0.1250 mol/L solution of hydrochloric acid was used to neutralize a 25.00 mL sample of potassium hydroxide solution. If it took 32.86 mL of hydrochloric acid what is the concentration of the potassium hydroxide solution? G: HCl(aq) + KOH(aq) KCl(aq) + H2O(l) [HCl] = 0.1250 mol/L volume HCl = 32.86 mL = 0.03286 L volume KOH = 25.00 mL = 0.02500 L

If it took 32.86 mL of hydrochloric acid what is the concentration of the potassium hydroxide solution? U: concentration of KOH nn V MR V S: volume  moles  moles  concentration HClHCl KOH KOH

  15. Highland Science Department Neutralization Calculations e.g. 1. a 0.1250 mol/L solution of hydrochloric acid was used to neutralize a 25.00 mL sample of potassium hydroxide solution. If it took 32.86 mL of hydrochloric acid what is the concentration of the potassium hydroxide solution? S: [KOH(aq)] = 0.03286L HCl = 0.164 mol/L

  16. Highland Science Department Neutralization Calculations e.g. 2. What volume of 0.150 mol/L phosphoric acid is needed to neutralize 38.5 mL of 0.250 mol/L calcium hydroxide?
