10. In your prelab, you wrote equations for the reactions of CaCO3 and zinc with two acids.
Considering your results for these reactions, is there a correlation between the rates of
cooctions for 6M CH3COOH and 6M HCl and the conductivities observed for CH3COOH
and HCl in part 1? Propose an explanation.

Expert Solution
Step 1

For the reaction of CaCO3 with 6M HCl and with 6M CH3COOH.,

CaCO+ 2HCl ---> CaCl+ H2O + CO2

CaCO+ CH3COOH ---> (CH3COO)2Ca + CO2 + H2O

For the reaction of Zn with 6M HCl and with 6M CH3COOH.,

Zn + 2HCl ---> ZnCl+ H2

Zn + CH3COOH ---> (CH3COO)2Zn + H2
