Interpretation:
The reason for a solution of 0.10 M HCl to be a better conductor of electricity than 0.10 M CH3COOH must be explained with drawing.
Concept introduction:
HCl is a strong acid and CH3COOH is a weak acid.
Answer to Problem 8E
The sketch of two solutions is shown below depicting ions and molecules.
Here, red dots represent H+ ions, black dots represent Cl- ions, green dots represent acetate ions and sky blue dots represent undissociated acetic acid molecules.
Explanation of Solution
From the sketch it is clear that in HCl there is complete dissociation, whereas in acetic acid there are very few molecules of acetic acid which undergoes dissociations. Most of the molecules of acetic acids are undissociated. Thus,number of ions is less in acetic acid. So 0.10 M HCl is a better conductor of electricity.
