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. 1.0 M HF has the same conductivity as 0.02 M HCl.

In Chemistry 12 HC 2 O HCO 3 - H+H+ The higher one on the acid side of the chart will be the acid and donate a proton. Weak acids and weak bases react but do not go to completion ( ⇋) ⇋ C 2 O H 2 CO 3 H+H+ BaseAcid 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 other side or the products are favoured. AcidBase

⇋ There are more products at equilibrium

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