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. 0 M HI is a better conductor than 1. 0 M HF has the same conductivity as 0. 02 M HCl.

In Chemistry 12 H+ ⇋ HC 2 O 4 - + HCO 3 - Acid Base H+ C 2 O 42 - + H 2 CO 3 Base Acid Weak acids and weak bases react 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 H 2 C 2 O 4 donates in the reverse reaction The acid on the left HC 2 O 4 - is stronger than H 2 CO 3 so the opposite side or the products are favoured.

Opposite side Favoured Stronger acid Reactants ⇋ Products There are more products at equilibrium

Complete the reaction H+ SO 42 - + H 2 SO 3 HSO 4 - + HSO 3 - ⇋ Acid Base Acid Reactants are Favoured because H 2 SO 3 is a stronger acid than HSO 4 - The stronger acid H 2 SO 3 more successfully donates its proton making more reactants. ⇋
