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.

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 (⇋)
⇋ C2O42- + H2CO3
H+
Base Acid
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.
