Acids Lesson 3 Acid and Base Reactions

Acids Lesson 3 Acid and Base Reactions. Conductivity The conductivity of an acid is determined by the number of ions generated in a solution and is therefore a combination of both the strength and concentration of the acid. 1.0 M HCl is a better conductor than 0.10 M HCl

  1. Acids Lesson 3 Acid and Base Reactions

  2. Conductivity The conductivity of an acid is determined by the number of ions generated in a solution and is therefore a combination of both the strength and concentration of the acid. 1.0 M HClis a better conductor than 0.10 M HCl 1.0 M HIis a better conductor than 1.0 M HF. 1.0 M HFhas the same conductivity as 0.02 M HCl.

  25. In Chemistry 12 HC2O4- + HCO3- H+ C2O42- + H2CO3 ⇋ Acid Base Base Acid Weakacidsand weak basesreact but do not go to completion (⇋) The higher one on the acid side of the chart will be the acid and donate a proton. Label all acids and bases- note H2C2O4 donates in the reverse reaction The acid on the left HC2O4- is stronger than H2CO3 so the other side or the products are favoured. H+

  26. ⇋ There are more products at equilibrium

  27. Complete the reaction HSO4- + HSO3- H+ ⇋ ⇋ SO42- + H2SO3 Acid Base Base Acid ReactantsareFavouredbecauseH2SO3is a stronger acid than HSO4- The stronger acid H2SO3more successfully donates its proton making more reactants. H+
