  1. Acid-Base Reactions SNC2D

  2. Neutralization The reaction between an acid and a base produces water (H2O) and an ionic compound known as a ????, which may be dissolved in the water or form as a precipitate.

  3. Neutralization The reaction between an acid and a base produces water (H2O) and an ionic compound known as a salt, which may be dissolved in the water or form as a precipitate.

  4. Neutralization The reaction between an acid and a base produces water (H2O) and an ionic compound known as a salt, which may be dissolved in the water or form as a precipitate. Example hydrochloric acid + sodium hydroxide 

  5. Neutralization The reaction between an acid and a base produces water (H2O) and an ionic compound known as a salt, which may be dissolved in the water or form as a precipitate. Example hydrochloric acid + sodium hydroxide  water + sodium chloride

  6. Neutralization The reaction between an acid and a base produces water (H2O) and an ionic compound known as a salt, which may be dissolved in the water or form as a precipitate. Example hydrochloric acid + sodium hydroxide  water + sodium chloride HCl(aq) + NaOH(aq)H2O(l) + NaCl(aq)

  7. Neutralization This ________________ reaction is also known as a ___________ because the products of the reaction are neutral (i.e. have a pH of ?).

  8. Neutralization This double displacement reaction is also known as a ___________ because the products of the reaction are neutral (i.e. have a pH of ?).

  9. Neutralization This double displacement reaction is also known as a neutralization because the products of the reaction are neutral (i.e. have a pH of ?).

  10. Neutralization This double displacement reaction is also known as a neutralization because the products of the reaction are neutral (i.e. have a pH of 7).

  11. Neutralization This double displacement reaction is also known as a neutralization because the products of the reaction are neutral (i.e. have a pH of 7). Another Example sulphuric acid + potassium hydroxide 

  12. Neutralization This double displacement reaction is also known as a neutralization because the products of the reaction are neutral (i.e. have a pH of 7). Another Example sulphuric acid + potassium hydroxide  water + potassium sulphate

  13. Neutralization This double displacement reaction is also known as a neutralization because the products of the reaction are neutral (i.e. have a pH of 7). Another Example sulphuric acid + potassium hydroxide  water + potassium sulphate H2SO4(aq) + KOH(aq)  H2O(l) + K2SO4(aq)

  14. Neutralization This double displacement reaction is also known as a neutralization because the products of the reaction are neutral (i.e. have a pH of 7). Another Example sulphuric acid + potassium hydroxide  water + potassium sulphate H2SO4(aq) + 2 KOH(aq)  2 H2O(l) + K2SO4(aq)

  15. Neutralization Some neutralization reactions will also produce carbon dioxide. Example hydrochloric acid + sodium bicarbonate  water + sodium chloride + carbon dioxide HCl + NaHCO3  H2O + NaCl + CO2

  16. Uses Neutralization reactions are useful on small scales, e.g. the formic acid (HCOOH) in a beesting that attacks nerves in the skin can be neutralized with an ammonia-based cream

  17. Uses and on large scales, e.g. lime may be added to an acidified lake to raise its pH: HNO3 + Ca(OH)2

  18. Uses and on large scales, e.g. lime may be added to an acidified lake to raise its pH: HNO3 + Ca(OH)2 Ca(NO3)2 + H2O

  19. Uses and on large scales, e.g. lime may be added to an acidified lake to raise its pH: 2 HNO3 + Ca(OH)2 Ca(NO3)2 + 2 H2O
