Question: Choose one justification statement between a-f that best fits the conclusion. I crossed out a few but I could be wrong. Thanks! Module II 3

Module II 3 - Objective: To explain why HCl is a stronger acid than CH3COOH - Results: The pH determined by pH electrode is 4.00 for 0.00010MHCl and 4.54 for 0.00010 MCH3COOH solutions. - Justifications in Discussion (Choose ONE of the following possible justification statements): E. Both HCl and CH3COOH react with NaOH to form salts. NaCl is a strong salt but CH3COONa is a weak salt. Doesn't explain why HCl is stronger (b) A lower pH was found in the HCl solution (pH=4.00) but not in the CH3COOH solution (pH=4.54) of same concentration (0.00010M). 24. Acetic acid is the main component of vinegar. (d) HCl completely dissociates to H+and Clin water: HClH++Cl, while CH3COOH only partially dissociates: CH3COOHH++CH3COO. One should always wear gloves when handling HCl because it is a strong acid. (f) H2 gas was produced when dropping a piece of zinc metal into the solution of 0.00010M HCl, while no reaction was observed when adding copper into CH3COOH solution. Conclusions: A 100% dissociation of HCl leads to more H+released than that of CH3COOH at the same concentration, thus HCl is a stronger acid than CH3COOH
