Methanoic acid is a weak acid and hydrochloric acid is a strong acid.
Describe the reaction with magnesium to show that methanoic acid is an acid.
______ HCOOH + Mg -> Mg(COO)2 + H2
Observations Mg ribbon gets ____________ hydrogen bubbles cause ____________
Compare this with a similar reaction of hydrochloric acid to demonstrate why methanoic is a weak acid and the hydrochloric acid is a strong acid.
______ HCl + Mg -> MgCl2 + H2
The rate of reaction for the HCl is ___________ than the rate of reaction for methanoic acid so there are _________ bubbles produced per second.
This is because all of the HCl breaks down to produce a higher concentration of _______ ions in the solution.
Weak acids set up an equilibrium and when _______ ions react the equilibrium shifts to replenish the _______ ions in solution.
For a given concentration and volume of acid
The total volume of _______ gas produced will be the same for both acids.
